While boarding a recent United Airlines flight to Mexico, Fred Glatz accidentally handed over his wife’s boarding pass. He says the agent pointed out the mistake but waved him onto the plane without asking for his own pass. As the couple settled into their seats, they had no idea that the unusual oversight would cost them $2,743.
The repercussions of the boarding pass mix-up didn’t become clear until they tried to check in for their flight home. Only one of them had a ticket back to Chicago — and it wasn’t Fred. As it turns out, United Airlines had marked him as a no-show for the flight to Cancun. That caused his return ticket to be automatically canceled, effectively stranding him in Mexico.
According to Glatz, United Airlines gave him no other choice but to buy an expensive first-class ticket to get home.
Now he wants UA to apologize — and refund him the $2,743 he otherwise wouldn’t have spent.
Glatz is hoping Consumer Rescue can make that happen.
But did United Airlines really require him to buy a first-class ticket in Cancun?
This case hinges on that detail.
Taking a United Airlines flight to Mexico (or did he?)
Last December, Glatz and his wife were looking for a short escape from the cold weather in Wisconsin. So they contacted their travel agent and booked a four-night all-inclusive trip to Secrets Cancun. The package included round-trip, nonstop flights from Chicago on United Airlines.
On the day that they were scheduled to go to Mexico, the couple arrived well in advance of their flight. They were eager to get the winter reprieve underway and ended up at the gate with plenty of time to spare.
When their boarding group was announced, Glatz opened the United Airlines mobile app on his phone. He pulled up the digital copy of his boarding pass and prepared to show it to the gate agent.
Glatz’s wife was ahead of him in line and scanned her boarding pass. Then it was his turn.
“I inadvertently had my wife’s boarding pass pulled up on my phone,” Glatz explained to me. “When the agent scanned it, she said, ‘Oh, you’re not Christine,’ but typed something into her computer. She smiled and then told me that I was good to go.”
Glatz and his wife were soon onboard the aircraft together and bound for Mexico.
But the official passenger manifest of the United Airlines flight told a different story. According to that document, only Christine had boarded the plane.
A United Airlines passenger “lost in the manifest”
When the couple landed in Mexico, the immigration officers stamped their passports and sent them on their way.
The next three days flew by and all too soon it was time to snap back into the reality of winter. After Christine got an alert to check in for their flight home, she signed into the United Airlines site. Immediately, she noticed something unusual: Fred had been removed from their reservation.
“We thought maybe it was just a glitch,” Glatz recalled. “We didn’t imagine United Airlines might have canceled my flight. I immediately opened up the UA chat to find out what was going on.”
Glatz then spent the remainder of his last evening in Mexico, trapped in a frustrating, nonsensical (and grammatically challenged) chat.
“Oh! Okay I see,” the United Airlines chat feature told Glatz. “I’m sorry about that and I truly understand cause this is also the first time I heard this issue. Cause when I check, something happened on your outbound flight. It shows the gate agent made a change on your ticket.”
That change on the ticket was significant. Instead of adding Glatz to the manifest, she had actually removed him from it. The chat agent went on to share what sounded like gobbledygook, which got Glatz no closer to having a flight home.
While telling Glatz not to worry, the chat message said the gate agent had marked him as a no-show in Chicago. After that, his name became “lost in the manifest.”
I’m still unsure whether he was communicating with a poorly programmed AI bot or an ill-trained human agent. The grammatical errors and frank admission of confusion led me to believe it might have been the latter. But either way, the outcome was the same: Glatz had no flight the next day, and he needed to get home.

Only one seat left to buy on this UA aircraft and it’s in first class
Hours later, when United Airlines had still not restored his flight, Glatz asked his travel agent for help. She was coincidentally also in Mexico at the resort with the couple.
“Even she wasn’t able to reach anyone at United Airlines who could restore my reservation,” Glatz explained. “The airline offered me a replacement flight in two days.”
Although he had enjoyed his time in Mexico, Glatz had no intention of extending his stay alone. He and his travel agent started looking for alternatives. His preference was to buy another ticket on the same flight and ask United Airlines for a refund later. But there was a problem with that plan.
“The entire plane only had one seat left,” Glatz recalled. “And it was in first class.”
Assuming that United Airlines would reimburse him after the original gate agent’s error was remedied, Glatz paid for the first-class ticket.
He would soon find out that it was a sorely mistaken assumption.
Asking United Airlines for a $2,743 refund
The next day, Christine and Fred checked in for their flight back to Chicago. When they boarded the aircraft, he sat down in first class. She went back to her original seat in premium economy and sat beside a stranger. The aircraft was full.

When they arrived home, Glatz began his quest to get United Airlines to reimburse him for that pricey first-class ticket.
Within days of submitting his refund request, the airline rejected it. That wasn’t surprising since he had actually taken the flight and enjoyed the amenities in first class. Glatz appealed the decision with the same results.
It quickly became clear to him that United Airlines had no intention of refunding him — for either flight. It now seemed that the airline had reverted to the idea that Glatz was a no-show for the original flight. If that were the case, then it owed Glatz nothing.
Realizing he needed additional backup, Glatz sent a request for help to Consumer Rescue.
Consumer Rescue investigates: What went wrong?
I went through the paper trail that Glatz provided to prove he was on the United Airlines flight to Cancun with his wife. That evidence included receipts for in-flight purchases and the stamp in his passport showing when he landed in Mexico.
Then there were the chat transcripts that seemed to indicate that United Airlines realized its gate agent had made an error. Unfortunately, the chat helper (human or bot) had no solution to the problem.
It wasn’t hard to see why Glatz had decided to take matters into his own hands and rebook himself.
However, rebooking himself had put his $2,743 in grave jeopardy.
Travelers should never lay out large sums of money on solutions to problems based on an assumption that they’ll be reimbursed later. This situation should have been easily resolved in Cancun with United Airlines putting Glatz in any available seat. That is, if the airline agreed it had canceled his return flight by mistake.
But that detail seemed to be back in question. It was time to ask our always helpful executive team at United Airlines what had gone wrong here.
United Airlines says it made a mistake, but…
After I shared the proof from Glatz that he had been on the flight with his wife, the United Airlines resolution team had a closer look at his complaint.
In a few days, there was somewhat of an explanation and a partial resolution.
The reservation team rebooked Mr. Glatz on his original economy ticket after the cancellation error [was noticed]. But he chose to fly on his new first-class ticket, so he is unable to be reimbursed for that reservation.
United Airlines executive resolution team
United Airlines went on to agree to refund Glatz’s original ticket, which amounted to just a few hundred dollars.
Although I was pleased that we now had established that Glatz was not a no-show on his flight to Mexico, something about this explanation still left significant questions. Most glaringly, there was the fact that a passenger can’t simultaneously hold two reservations on the same flight. If the United Airlines reservation had reinstated his ticket, he would not have been able to book the first-class ticket on the same aircraft. He also would have been able to see his flight restored on the mobile app.
Now I just had one more question for Glatz.
Did United Airlines offer to reinstate the premium economy at the gate?
I went back to Glatz to find out if he had declined an offer at the gate to return to his original seat.
“The information that your United Airlines contact has is incorrect,” Glatz told me. “No one offered me my seat back or I would have taken it. Also, if my original flight was restored, why couldn’t I see it on my mobile app?”
A very good question, indeed.
I went back to the executive team at United Airlines with the additional information and requested clarification about the timeline of the reinstatement of Glatz’s seat. It seemed to me that there was still no clarity about what happened and why he wasn’t aware of his seat’s reinstatement — if the reservation team had restored it.
Surprise! Here is your full refund from United Airlines
Faced with the ongoing lack of explanation and clarity about what really happened at the gate and at every step thereafter, United Airlines agreed to refund Glatz’s first-class ticket.
“Yes, Michelle, we’ve just gone ahead and refunded the $2,743,” my executive contact at United Airlines confirmed.
But just as Glatz was breathing a sigh of relief, United Airlines showed him this fiasco wasn’t quite over. The internal confusion at the airline was still going strong.
Glatz had filed a complaint with the Department of Transportation at the same time as sending one to Consumer Rescue. As the DOT does, it had forwarded the complaint to United Airlines for its review and response.
Coincidentally, United Airlines responded to the DOT complaint on the day after it agreed to reimburse Glatz. Now, the airline was once again calling Glatz a no-show — but this time on the flight home from Cancun.
Hello Fred,
We’ve received a message from the United States Department of Transportation regarding your flight on December 8, 2025.
I’m sorry about the confusion with your ticket. I want to make every effort to ensure your concerns are addressed.
In review of the confirmation number; ***** or records indicate you were booked in economy and traveled on December 04, 2025.
Our records indicate you were a No-Show for the flight on December 08, 2025, that was booked in economy.
United Airlines customer service
The good news is that Glatz received his $2,743 refund despite this response to his DOT complaint.
And he’s happy to finally be able to put this unpleasant experience to bed. But one thing is positive: Fred will never board a flight again without making sure the agent has scanned his boarding pass.
That’s a lesson we should all learn from his experience!

What to do if your airline mistakenly marks you as a no-show for a flight
The good news is that it is a rare occurrence for an airline to mistakenly mark a passenger as a no-show. However, my case files show it does occasionally happen — and not just on United Airlines.
Related: Why did American Airlines mark me as a no-show on a flight it canceled?
Here’s how to reduce the chances of it happening to you — and what to do if it ever does.
Make sure you’re handing the gate agent your boarding pass
Fumbling for your documents at the jetway entrance can lead to boarding pass mistakes. It’s a good idea to have yourself organized and ready long before the airline calls your boarding group.
When you reach the front of the line, pay attention. Does your last name appear in the scanner? Did you see a green light? All of those are signs that you’ve been added to the final passenger manifest and won’t be marked as a no-show. If there are multiple passengers in your group, each adult should hold their own boarding pass to reduce the risk of mix-ups.
Download the airline’s mobile app
You would be hard-pressed to find an airline without a mobile app in 2026. By downloading your airline’s mobile app, you can receive real-time updates on your flights. You’ll have a digital copy of your boarding pass that you can easily scan before you get on the plane. You can see in real time if the agent has successfully scanned your boarding pass. If you’re already on the plane and notice a problem, you can have it remedied before you’ve even left the ground. Before the aircraft pushes back, is the best place to fix a boarding pass scanning error.
An added bonus of downloading your airline’s app? You’ll never accidentally fall for a scam call center because you’ll always have the airline’s official number through the app.
Ask the airline to reinstate your ticket
If you belatedly discover, as Glatz did, that a gate agent marked you as a no-show and canceled your return ticket, ask the airline to reinstate it. You will likely be asked to provide proof that you were on the flight in question. You can do that by showing receipts from in-flight purchases, passport stamps showing your arrival date at your destination, and time-stamped photos taken of yourself there.
Don’t buy yourself an upgraded ticket expecting the airline to refund you
If an airline cancels your return flight and refuses to reinstate it, you can purchase a replacement ticket. However, if you expect the airline to refund it later, it is imperative that you don’t upgrade yourself. The Department of Transportation does not require an airline to pay for an ungraded ticket in this circumstance. So it’s crucial to make every effort to allow the airline to rebook you, or confirm your own replacement flight in the same category as your original ticket.
After you’ve returned home, submit your receipts to the airline for reimbursement. If you need help finding the right person or department to contact, you can make a request to Consumer Rescue’s Research Valet.
