If you are in for something unique try PEN
which can be flonw on FY (ATR 72-500), AK
(A320-200) or MH
(B737-400) which is an amazingly short hop with a block time of 30 minutes.
Like what MHG
mentioned, you can also get on Berjaya Air's Dash-7 flight (which is pretty much the only place you can get a Dash-7 in Asia these days IIRC, minus those minor Indonesian carriers which I'm also unsure if they do fly those).
Although non-domestic, you can try flying Wings Air PEN
also on an ATR 72-500. It's an pretty unusual airline that little has heard of. Another choice, although not unusual or rare aircraft would be flying AK
to anywhere else and try their famous Nasi Lemak which is one of the nicest meals I have ever tasted in the air (yes the taste is even comparable or better than the F/J meals I've had).
Agree with the nice airline part but not the low fares. Their prices were always exorbitant when I check. They did manage to offer a nice deal for KUL
(on their B738 which has been phased out from the airline) for a little more than 50 MYR
all-in once though, but that's all. Their ATR flights are pretty expensive by Asian standards.
Also as reifel mentioned you can try One-Two-Go (subsidiary of Orient Thai) who flies MD
-80s from DMK
. A good chance to use Bangkok's old airport! You can also fly BKK
on Bangkok Airways (PG) as they offer lounge access to all passengers, even Y class, in BKK
airport is totally open air which I think is pretty interesting although I have never been there myself.
