My flight from MKE to DCA today was noticibly different today under the new Frontier brand.

1) The flight was overbooked by 4 seats. They asked for volunteers who would get $200 if they took a flight routed through Omaha. Evidently both afternoon flights to DC were overbooked. That seemed unusual.

2) My flight was delayed 2 hours due to a mechanical problem with the door. However, they gave everyone a $100 credit voucher for Frontier. That was certainly a nice surprise.

3) The exterior of the plane was still Midwest blue but the interior had been refitted with the green Frontier seats including the stretch seating at the front (it looked like first 4 rows had stretch). I also wonder if this is why the flight was oversold. I had originally booked on Midwest and I am pretty sure that the flight showed the standard configuration of 19 rows when I booked. When the flight was rebranded as Frontier, I got a notice that my seat assignment had been changed from an aisle near the front to a window in the rear. When I contacted Midwest to ask why this happened, they changed my seat assignment to an aisle in the front and it turned out this was a stretch seat.

4) Finally, I've flown this route twice in the last 3 weeks and both times they have given out only one cookie. I heard the flight attendent say "we're down to one cookie now" a couple of weeks ago, but thought she just meant that particular flight. I'm guessing the cookie quota has changed.
