i haven't been down there in 2 years, but at that time, pr was the exclusive tenant of t2 (nice new terminal) while all the other international flights were relegated to t1 (very old and run down). meanwhile, other domestic carriers had to use a very, very old terminal on the other side of the field, which required a 10-minute taxi ride from the rest of the airport.

also, at that time, t3 was 90% complete, but gridlocked because they changed the rules at the last minute and the german financer (frankfurt airport group?) wanted out. the government put it up for auction to try to raise the required buyout funds, but noone was willing to pay anywhere close to enough money to facilitate such. my company was actually one of the bidders, but we were only able to offer roughly half of the expected takedown because that's what the numbers warranted (even then, methinks we still would have been taking on far too much risk, considering the troubles encountered by the germans).

pr had long opposed t3 because: 1) it would have given up its position as having the only nice terminal in the airport to itself and 2) would have been required to move its international flights to the new terminal and pay its share.

since i've been out of thre loop for a while, i have no clue about the current state of affairs, but if i had to venture a guess, i'd say that little has changed.
