This traveler made a passport mistake that ended with her in "jail." Here's how you can avoid this fait.

Welcome to Switzerland. Now you are going to jail!

Elena Pavlova just made the worst travel mistake of her life. Before setting off for her dream vacation to Europe, she neglected to check the entry requirements for Switzerland. Then she managed to board her Swiss Air International flight (SWISS) to Zurich with an invalid passport for her itinerary to the Schengen area. Not surprisingly, her vacation plans came to a screeching halt when she landed. She was denied entry and border police took her into custody.

Now Pavlova is asking why SWISS allowed her to board the plane with an invalid passport in the first place. And she’s demanding that the airline share the $3,000 cost of this travel mistake.

It’s critical to know and possess the required entry documents for your intended destination. If you don’t, you too may take an unpleasant international round-trip odyssey — no vacation and no refund included.

It is not possible to use a library card to fly internationally. So why did this passenger think she could?

No, it is not possible to fly internationally with a library card!

Elgy Gillespie was on her way to the airport for a trip to Ireland when she lost her passport. No problem, she thought. Having recently read an article that suggested she could fly with just a library card, she was confident that she could talk her way onboard her international flight.

But when a Norwegian Air Shuttle agent unequivocally denied her boarding without a passport, she was stunned by his lack of understanding.

Now she wants our advocacy team to intervene.

Elgy’s story serves as a warning not to believe everything you read online. It also is a reminder of the importance of ensuring that all of your required travel documents are firmly in hand before stepping up to the airport check-in counter.

If you lose your passport on your flight, you could end up in jail. This passenger found out the hard way.

I lost my passport on my flight and ended up in jail!

At some point during her international flight from New York to Madrid, Alberta Chen lost her passport. As a result, she ended up at the immigration window in Spain with no passport to show to the officers. What happened next was a traveler’s worst nightmare. Chen was taken from the airport, placed in detention overnight and then deported back to the United States the following day.

Now she wants to know how she can get a $2,400 refund for this vacation fiasco.

Alberta’s distressing misadventure underscores the importance of safeguarding your passport and other travel documents at all times. If you don’t, you might find yourself in a similar predicament on an express round-trip international journey — no sightseeing included.

This passport mistake is one that will easily ruin your vacation. This traveler wishes someone had told him sooner.

This passport mistake will ruin your vacation every time

Trevor Seamon made a devastating passport mistake, and it ruined his family’s dream vacation. In all the preparation for the journey to Italy, he neglected to check the validity of their passports. That error led the Seamons to arrive at the airport with passports expiring within 90 days — invalid for travel. Denied boarding, they missed their eagerly anticipated trip and ended up right back home at the end of the day.

Seamon believes Air France is responsible for this passport mistake, and he wants our team to negotiate a refund. But is the airline responsible for the family’s ruined vacation?
