Thanks Gardyloo. I'm based in NYC so I have access to most airlines from here. I tend to fly AA/US BIS for work enough to qualify for Platinum on AA and maybe more if things line up just right. More flexible on leisure trips; recently we've flown LH, AZ, have EI and VA coming up. Other than that I tend to accumulate miles from credit card signups. The three "miscellaneous" miles I have right now (AS, LH, AV) were from credit cards. I don't do much in the way of MS, maybe a couple thousand a month, if that, depending on what I have access to and when. I have thought more about AS (particularly given partnerships with both AA and DL). Right now the main benefit I get of AA status other than the extra RDMs is getting the 'economy plus' seating for free when I have to fly in the back; I've got a bunch of AA upgrade stickers that I have not really tried to use (just a couple of times on transcons where I didn't clear). I like early boarding but can live without it; I like priority lines for security but have Pre-Check so that takes care of that. I can get lounge access from some credit card or another, and status doesn't get lounge access on domestic itineraries anyway.
