I've been trying to make a flight change for the past hour - both on their 'new' web portal and on the mobile app - and it stalls endlessly at the "It will take a moment to complete your transaction" stage. No error message, even. Have tried three different credit cards, so it isn't that either.

Anyone else having issues today? I am nearly banging my head against the wall. Why can't they ever get their IT together?

EDIT: Finally got it to work by using a different browser and clearing the cache...ugh.
