They don't stack.
To get the *A Gold benefits, do I have to add my A3 FF # to my reservation or can I just show the card at check in and leave my UA FF # in the reservation?
How do I know if the people traveling with me on my itinary will also get an extra bag? I need to know specificly for Luftansa, LOT and Austrian.
Do passengers flying with get the status benefits?
Yes.
If you trust Dan...
Pretty much the only airline that gives benefits to everyone on the reservation is UA, and maybe AC. For virtually every other carrier, assume that only the elite member will get the benefits, unless you hear from someone explicitly otherwise.
@yehuda that's a record amount of misquotes and out of context quotes on one page.
I thought the DDMS post about it said you get 1 extra bag above what you're entitled to.
Pretty sure DDMS says you need to leave A3 on there and once you're in the lounge, call UA and have them switch it back to UA FFN so you can earn your miles there.
This is my original Q and the second post down is your response. I only part of my question because that's what you do.
Incorrect. Can be done right at the kiosk or checkin agent.
@Dan and all others, can I leave myit UA FF # and just flag my A3 Gold card at the lounge/boarding/baggage drop off and avoid the hassle of changing the FF #?
