Flight out of Tampa was delayed 2 hours and 40 minutes. Kudos to the gate agent who moved me to the front of the plane so I could disembark to catch my next flight from Philadelphia to Bangor. Things were looking up to catch my 2nd leg when we landed fifteen minutes earlier than initially predicted after our late departure. This was all for nought when we were not able to get to our gate. Had to go from concourse "C" to concourse "E". There is a shuttle bus no bus or staff was present. Decided to walk it and arrived just prior to gate closure. We the sat on the tarmac for another 45 minutes waiting for the flight deck crew to arrive.
