There is a financial aspect to this. Tickets WILL go up. AAA teams travel by plane, not bus.
For the whole International* League the distances are much greater than within the Southern League. However, for the Southern Division, where we would (presumably) play most of our games, the distances are comparable, averaging about 400 straight-line miles.
The teams do not have ticket information posted on their websites, so comparing prices isn't possible right now.
* the International League, by the way, is not international, all US teams.
If they can stay under 500 miles then they're good. Anything over 500 must be traveled by plane. If they do move to the Southern Division, then their Division opponents would be Charlotte, Durham, Gwinnett (Atlanta), and Norfolk. Norfolk would be a plane, and Durham would likely come down to where the stadium was (downtown to downtown is 478 miles). Charlotte and Gwinnett would be fine by bus.
In looking at the Norfolk Tides schedule, they look to play their division opponents 16-20 times, while their out of division teams they play 6-10 times. Now assuming half were home, that's still a fair amount of games far enough that they'll need to fly.
Now, it's the minors - things aren't perfectly balanced like MLB or the NFL. In the IL the North, South, and West divisions have 6, 4, and 4 teams respectively. The International League is an eastern US league - their "West" division is Columbus, Indy, Toledo, and Louisville. They do TRY to help out the teams a bit so travel isn't a giant expense. At the same time, some amount of air travel is probably desired for development, considering that AAA is the last stop before MLB and almost all travel in MLB is by Plane.
Players are paid more, but thankfully that's a issue for the parent club (coaches as well) that Miami has anyway.
Additionally, I'd like to compare the stadiums when I have some time - 121 Financial is nice for an AA team, but there may be some stadium work if this does come to fruition.
