I hope to do this round-the-world thing in the summer with *A and there are two segments that I am slightly worried about.
YYC - IAH - EZE: YYC-IAH is with AC and IAH-EZE is with UA. There are 4 hours in between... but I was wondering if my bags would be checked through to Buenos Aires in this case? And do I need to go through immigrations in Houston?
EZE - GRU - LHR, all with JJ (TAM). Can they be trusted to check my bags through all the way to London?
Thanks a lot!!
