UA15/UA17 confusion
Hello all, firstly apologies if this is in the wrong place, brand new poster here.
I am due to fly LHR-EWR soon, the booking was made on flight UA15. I have been tracking it on FlightRader for a few weeks, only to find the 15 flight has disappeared. I've now had an email saying my flight times have changed, and the number is now UA17.
However, when checking the status of the booking via the app and online, both are showing different times and flight numbers, so I am a little anxious as to which one is correct.
I would really appreciate any insight, thanks so much.
