The husband and I paid for my sister's tickets to the family trip this summer in BVI. We are flying SFO-EWR-STT and then take a ferry.

We are in PS BF SFO-EWR and she has no idea. She asked a couple weeks ago if there a chance for an upgrade since I'll have Gold status by the trip. I said something like "who knows?"

She has the confirmation email with the seat number in it, but she is not a details person and hasn't noticed.

I'm trying to decide when/if I should tell her. I'll bring her BP to the airport, so it is possible she won't realize it until she is walking on to the plane and has to turn left :P
