I was on Celebrity so it could be different on HAL. It wouldn't matter unless you were a big Christmas fan, I took Christmas bon bons to Antarctica with me so we could put Christmas party hats on on the flight home on Christmas day. My daughter was absolutely horrified when she saw what I'd done. Needless to say we went hat less! However, I had a win with 5 hour lounge access in Santiago on Christmas Day. Seems we were entitled to it on the way over, but not on the way back. due to code sharing. The girl on the desk changed her mind and relented to let us in because it was Christmas day,
