how far does my baggage go? [allowance for upgrades]
Hi to all those dedicated evangelists and moderators. ^ I’m asking for advice and I can’t find an answer in the archives although I bet it’s been addressed before. If I upgrade to biz with 500 mile credits on an international flight (for the domestic portion of it), will my checked baggage allowance of 3 (75lb) make it all the way to my international destination without having to lay out extra $$? I understand that the final international leg of the flight probably won’t be honored in biz, but what about the luggage? Any help would be humbly appreciated.
