I just flew on SCA from JFK to MSP last week, and from what I picked up, they have 5 737-800's for the summer season and have leads on 4 more for the winter season. The planes are great, all leather and really comfortable looking first class seats. the have brought back 28 pilots, all to start training soon. They also have a few old guys retiring in the next few months, my informent being one of them. The staff was nice and seemed happy though.
