The
TPA situation has really changed over the years. When the terminal/airside first opened up with four airsides, four signatory airlines were responsible for the design and operation of each airside. The four were Delta, Northwest, Eastern and Delta.
National and Eastern had significant operations at the time. While additional carriers used the extra space at the Delta and Northwest airsides. TWA and United for instance.
Pan Am bought National and operations dwindled from that quarter. Deregulation brought a bunch of new operators. Ozark, Piedmont, USAir, American,Continental, etc...
Northwest operated a mini-hub at
TPA before the Republic merger, then dumped it to concentrate on
MSP/
DTW/
MEM.
Piedmont used
TPA extensively as a result of their "Florida Shuttle" experiment, this carried over for a time after the merger with US. For several years US was
TPA's largest operater (Express included).
Eastern went belly-up and Airside B was closed. Delta has a new airside while their old airside C is being rebuilt for Southwest.
Now, history aside, I don't think
TPA's facilities are too large for the airport. They have the room to grow and they have the forsight to rebuild old airsides and build new ones as needed, BEFORE the existing facilities become saturated. There's also room north of the existing terminal complex to build a virtual twin of the current terminal/airsides.
And when it comes to airports, it's almost always a good idea to have more room than needed at the current level of activity.
TPA can serve the Bay Area for perhaps DECADES to come.
And they have a perfectly good reliever airport in place at
PIE should things get crowded at
TPA. I think most older airports would KILL to be in
TPA's position.
