I catch a flight booked through United beginning of July from LAX to ZRH and I'd like to get a cash upgrade to the business class. When I started to read myself in, one thing that confused me was the letters... I only flew once Swiss and than only Economy so I didn't really pay attention to it. Can somebody (try) to explain it to me? Do I need to ask for a certain "letter upgrade" at the check-in or can I just ask for a Business Class upgrade? I was booked on Economy (T).
I've also read a bit in the big thread here (
https://www.flyertalk.com/forum/swis...-swiss-19.html) about the numbers... So I guess somewhere between 1100-1500$ should I expect to pay for the upgrade?
