How do I prevent an airline from finding out that I am a multinational?

How do I prevent an airline from finding out that I am a multinational? - Frame with text placed on blackboard with sterile mask

Normally, when flying on a return ticket, I would present the airline with the passport that lets me into the destination country during check-in. This will sometimes result in showing two different passports (depending on whetever I am returning) with the same return ticket. However, quite obviously, this theoretically allows the airline to deduce that I am a multinational, and which two countries exactly am I citizen of.

Let's assume I didn't want the airline to know. What would be my course of action? Should I just avoid booking return tickets? Do you know any other tricks?

Edit: for the purposes of this question, let's assume I don't care if governments know or find out that I am a multinational. Just the airline.



Best Answer

In general you can't. The airlines are responsible to check that you have proper entry documentation for your destination and will often be heavily fined if they screw up. Hence they do keep records so they can show What they did in case a dispute arises. These records are associated with the ticket number and quite often with you as a person.

Whether they every look at these records, compare docs, or care at all, is a different question, but you can't be sure.

To really achieve your goal, you would have to buy one way tickets with different airlines and use these airlines consistently for each direction.

Can airline deny boarding?

Yes unfortunately airlines can refuse boarding or remove a passenger from a plane for any reason at all. Even of the passenger has paid full fare for the ticket. Passengers do not have many rights when it comes to being on an airline.

Will airlines tell you if someone is on the flight?

No. Only way somebody else can check your reservation is if that person knew your name, flight number and the reservation code. Even then, they would not know if you boarded the flight. No airline will give out the passenger list of a given flight.

Where do we check in and get a boarding pass?

Paper boarding passes are issued either by agents at a check-in counter, self-service kiosks, or by airline web check-in site.

Answer 2

What would be my course of action?

There's a few options:

  • Book the return flight with a different company
  • In case one of your passports allows for visa-free entry to the other, show that passport at all times. If not, apply for a visa to the other country through the second country (but don't use it at immigration).
  • Fly to an airport in a neighboring country that is visa-free to both passports and then get a separate return ticket to that airport.
