Hello! I'm not sure this is the right place to ask this but I'm flying transatlantic with EW Discovery and am being offered an upgrade to Premium Economy for 180 EUR or Business Class for 460 EUR on the return flight. I was wondering how common these prices are? Both seem reasonable to me on a 700 EUR Economy return ticket.
I'm looking to purchase other transatlantic flights so if this is common, it might be worth it to book Economy and upgrade afterwards. Or am I wasting my time with EW Discovery upgrades?
