I don't like the amount of seat space (too small) and the fact that the seats hardly tilt back.

Seattle Airport may consider better deicing procedures.The flight from Seattle was delayed 1.5 hours - we waited for deicing of the airplane sitting inside the aircraft. As a result next trip has been rescheduled to next available flight and trip became very long.

Our bags did not arrive on time, but were delivered to our destination the next day. They accomodated an extensive list of items we needed to purchase for our two children and provided us with miles credits for them not arriving on time. Good service by Tristyn in Detroit baggage.
