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

[EX Q]: Flights out of London Heathrow do not contain departure gate information until about 45 minutes before the flight is ready to depart (presumably so you spend more money at the duty-free). Are there any public APIs or resources that will tell me which gate my flight departs from before the Heathrow departure screens do?

[EX A]: Determine gate for departing Heathrow flight

[EX 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?

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

However he was refused based on these reasons:




How do we rectify these points stated and can he reapply straight away?

Visa got refused again


[EX A]:
Visitor visa refused!
