LAX to LHR, buy upgrade to Y+ online or counter
Hi all,
I'm flying LAX to LHR during a Tuesday night. I booked Y seats and was hoping to upgrade to Y+. The cost online is $735. Two questions,
1. Is it usually cheaper to buy at the counter, or is it standard pricing based on segments?
2. Do you think upgrades will be available at the counter?
Thanks, and sorry if this is a duplicate post.
