We flew round trip CVG-TPA on what was initially supposed to be a Delta MD88, but about a month before departure, changed to a Delta Connection/Endeavor Air CRJ900. That is one tiny little bird. Banged my head on the doorway getting on the plane, had to duck under the "EXIT" sign in the aisle and squeezed into my window seat. Newer birds, N299PQ and N306PQ, both about 4 years old and nice flight crews but not somewhere I'd like to spend a lot of time. On a more positive note, we had a great time in Siesta Key.
