Given a travel related situation, and given a specific question about the situation, summarize the question into a title

Q: I have an ESTA for the US, valid until Mar 20, 2020. I have confirmed the ESTA is still valid on the U.S. Customs and Border Protection site. However, the airline I have a flight booked with will not allow me to check in online due to not having a valid ESTA/VISA/etc.

Does this mean I'm not going to be allowed on the flight or is it simply a problem with the online check-in? And if I'm allowed on the flight, should I expect issues on arrival in the US?


A: Valid ESTA for US, but not allowed to check-in Online

Q: Take for example this flight:



in 45 minutes you have to go through immigration, security checks, and probably you need to go to a different terminal: it's basically guaranteed that you can't catch the connecting flight

If I lose this connecting flight, are airlines required to find a replacement flight to me? (possibly without charge)


A: If security checks during a layover take too long time and I lose the flight, would the airline find me a solution for free?
