Just booked a return trip for next week from DFW to New York, connecting through DTW. The first leg is on an A-319 booked in K class. The seat map shows no available seats.
What is the significance of this? Is the coach cabin really sold out and if so why was I able to get a reasonable K fare? And are there that many other elites on this flight that all the "preferred" seats are taken? I'm guessing an upgrade for a Gold will be unlikely in that case, but any advice on how to avoid getting a middle seat? Thanks.
