We're going to GCI in April, starting with IAD to LHR, booked in J for myself and Mrs. G.
The POUG offer from J to F is $1097 each way for both passengers, so $548 per. Not entirely out of line.

But, upgrading the round trip is $3197 ? That math is bonkers, $1003 more than individual upgrades.

If I pick one leg, is the other leg going to immediately double in price?
