Which Airlines are NOT Booking Middle Seats
American, United, JetBlue, and Spirit are filling planes according to this article in USA Today:
I'm a BIG Southwest Airlines fan here in Chicago due to Companion Pass and no cancelation charges (among many other reasons) so I was thrilled, relieved, and proud to hear of their decision.
How do you feel about your "airline of choice" choosing to book middle seats or keep them open???
