Just seeing this post. I'm a MSY commuter. I did NYC for a few months. I always got a seat and even got 1st a few times. The bad part was when IRROPS hit the NYC area, but I never competed with another pilot. ATL would be very easy though. Sure there are a handful of DL pilots down here, but there are enough flights that as long as you give yourself 2-3 chances, you'll be good. I did IAH and now I do ORD. I too miss the ease of IAH too. Sure I competed with a few mainline United pilots to IAH, but there are plenty of flights if you give yourself a few chances. ORD is okay, but there I miss the frequency of flights I had with IAH. The short 45 mins. to 1 hour makes commuting tolerable. DFW is doable too.
