Centurion Lounge is opening in LGA.
As much as I strongly dislike #deltasucks and #luv SWA. I think delta is the correct choice. While the benefit of companion pass is unparalleled, the most A-List will do for you is upgrade your boarding position. With #deltasucks you can attain medallion status and receive business class upgrades, priority boarding etc.
As mentioned above you can get Companion Pass like I did through CC offers. If you do, take your wife, kids, family or friends...
