A side note: we missed our connection in Memphis because we sat on the tarmac in Mobile for an hour and a half. Luckily, there was a flight leaving Memphis going to Greensboro, NC (which is about 85 miles from our house but a better choice than spending the night in Memphis). The catch was that the flight to Greensboro was boarding from gate C44 as we talked to the agent at gate B30-something. We had to sprint - carrying baggage - down the entire length of both terminals to make the flight. Even wearing cute wedge heels, I have never run so fast in my entire life.
