why just united?
Everyone keeps jumping (or threatening to) United....why
There is DL, AA and a host of others.....why stay in *A?
I have found CC's that get most lounge access AND including PP, plus Nexus/GE gets you through most long lines......
So stop chasing any alliance and shop by fare...you will do much better....really analyse the cost of chasing QM and you will soon realize it's just not worth it in most cases (paid corporate travel w/b only reason i could see and only if yu are allowed the right fare bookings)
I mean most lounges are garbage anyhow and upgrades are becoming LMU sales so stop drinking the Kool-aid!
