Anywhere you've got the combination of soldiers and alcohol you can find service fights.
Service flights, on the other hand, are few and far between nowdays - I recall in early 2002? the support flights in and out for 3 VP were cunningly planned to leave Trenton on Thursday night, stop mid-day Friday in Greece, come back through Greece on Sunday afternoon, and return to Trenton early Monday. So, for a few days of leave, a service member could get a weekend in Greece... a pretty jammy go for those who pulled it off.
There are still some flights; from what I recall most stop in the UK. As Supersonic Max said, there should be a link on the Trenton DIN page.
(Then there was the mis-directed email I got one February, detailing the plans and flight itineraries for the small unit exchange in Hawaii. I cursed and forwarded it to the intended recipient.)
