It's an Express Jet flight and I'm not surprised by the delay -- we had one recently with them where

1) the crew as late arriving

2) everyone got on the plane

3) we backed out and they found a mechanical problem that said could be fixed on the spot, but

4) we waited for some one to wave us back to the gate and for someone to move the gate back into position

5) we waited for a mechanic to come and do his thing

6) we had to refuel and wait for them to come do that

7) finally left and got to our destination only to find

8) another plane at our gate and were delayed another 30 minutes.

All together we lost two hours !

Yet another reason to avoid CRJ 200's
