My middle seat did not recline. When I asked the flight attendant for help she said it would be a quick flight and we'd be there soon. Given that it was an evening flight that I had to reschedule after two flight cancellations from a different airport, that required a bus ride to a different city, I was really hoping for a quick nap.
