The website was working again earlier today for me. I was able to see the flights but I had to leave before I could make a decision and book the alternate flight.
I am back now and I can still log in via the phone app. I was able to change the flight I needed. But I can’t search new flights on the app. I deleted and reinstalled the app and still can’t search for new flights.
I’ll try clearing all the cookies on Firefox and Brave in the morning and see if that fixes these glitches.
