Further to the tel nbrs above I can give you an e-mail address for Panaero.
It is
[email protected]. I used them a couple of years ago to fly to JTR too and they were ok!
They are operating SenecaII and Cherokee6. As far as I know you will need a check flight, but you can get more info through their e-mail.
JTR is a dream place! Enjoy it!
