Kids need passports too, children must have passports to fly internationally, passport cards aren't for flying

Kids need passports to fly internationally. Why didn’t this mom know?

Just like their parents, kids need passports to fly internationally too. But Kim Ross wasn’t aware of this requirement. She says the travel agent she used to book her family’s dream vacation never informed her. But when the family tried to check in for their flight to Turks and Caicos, Delta Air Lines quickly broke the bad news. Without passports, Kim’s children weren’t eligible to fly internationally, and the airline denied boarding to the family.

Kim blames her travel agent for their ruined vacation. But is that a fair place to put the blame for being unaware that her kids needed passports?

What’s the worst nightmare that could happen if you land in Mexico with expired travel documents? Kush Kanna’s wife recently found out in a most unpleasant way. She thought she was heading for a relaxing tropical vacation in Costa Rica with her family.

Hurt on vacation, travel insurance mistake, going to the hospital in Mexico, Expensive medical treatment abroad.

Hurt on vacation? Don’t make this travel insurance mistake

After she was seriously hurt on vacation, Molly Brooks made a giant, but not uncommon, travel insurance mistake. She left the rural Mexican hospital where she received pricey emergency services and flew home without any documentation of treatment. Her only evidence of hospitalization was a non-itemized $6,000 credit card receipt. As could be expected, this lack of documentation presented an insurmountable problem when she filed her travel insurance claim.

No, United Airlines will not refund your business class upgrade after you take the trip. So why is this passenger asking?

This United Airlines business class upgrade wasn’t worth $999. I want my money back!

It’s not likely that any airline would refund a business class upgrade after a passenger completes the trip. But that’s precisely what Juli Talec says an employee of United Airlines promised to do before her recent upgrade.

Juli insists that she never intended to pay to boost her seat into the elite section of the aircraft. So why did she sign a credit card receipt for the business class upgrade at the United Airlines check-in counter?

That’s the $999 question of the day.

This traveler says she didn't damage her vacation rental unit and doesn't want to pay for the repairs.

I didn’t damage this vacation rental! Do I have to pay for it?

Could you be falsely accused of causing damage to your next vacation rental — and be forced to pay for it?

Colleen McKenna is sure that the answer to that question is “yes.” She just returned from what she thought was a peaceful and uneventful stay in a rented condo in Hawaii. But the property manager says she and her husband caused significant damage to the vacation rental during a domestic disturbance. As a result, he charged her credit card for cleanup and repairs — several days after the couple’s departure.

Colleen says she has absolutely no idea what this man is talking about and believes it’s a scam. Now she’s asking our advocacy team to investigate.
