Evening,

Would someone be able to answer a couple of questions I have with regards to AC Altitude flying on United? I have received my 75K altitude from flying within Canada (which gives perks with star alliance) and I would like to know how to use them with United in January.

1) If I read it correctly to access the united star lounge in Houston I show them my United boarding pass and my AC 75K card?
2) Do you get any kind of priority screening(not likely in YYC as you go through customs), and priority boarding. I booked my ticked with my united membership not AC.
3) Long shot, can you get any kinds of e-upgrades with the AC credits.
4) Do the airline systems talk to each other so they know you are a Altitude member(or would I have to had put in my Aeroplan # when I booked)
5) anything I am missing

Sorry, did search and could not quite find the answers.

Cheers,
Sean
