Hi, new forum member and pretty new to to whole miles game. I have all of my miles with Continental but have been looking at fares for an upcoming trip ORF-LON, Delta and United have the best fares and most convenient schedules for me right now. My question is would it be better to book with Delta and transfer the miles to my Continental account(can I do that?) before the switch or go with United? Thanks, any advice is greatly appreciated.
