I have flown Ted from Tampa to DC for 2 round trips in the last few months and have found them to be very good. They have arrived on time for the most part and service has been great on the airline. There is a good selection of drinks on the plane, and also they show a selection of TV shows on the DC route, which help the time pass nicely. Prices are cheap if you book early, but can get expensive as you get close to the date.
On the downside, there can be limited overhead storage space .
