Mrs Chugger and I are flying MIA to BRU in April. She is a FA and we fly Id90. I just flew LX to CPH from MIA. The flight itself was fine, but we didn't receive the approval for the non-rev flight from LX until an hour before I had to leave for the airport, despite numerous calls to my wife's airline's travel department and submitting the request 2 weeks prior. I can't go through that stress again but I like LX, have used them before and like transferring through ZRH. It's a breeze.

BA has an agreement with Mrs Chugger's airline for ID75, tix would be a little more and we'd transfer out of LHR. I've read horror stories in TS/S of immigration at LHR consisting of long lines and endless interrogation, but would we go through the same immigration if we are just connecting out of LHR for final destination of BRU?

Third option is LH, ID90, connecting out of MUC. What a great airport. Been there before. Any airport with a beerhall is okay in my book.

Any suggestions from the super frequent international flyers would be appreciated. Thanks.
