I think ASD has been in the game longer than Aeromar.
Air Europa created it and then S.A.P. bought it.
S.A.P. it's a big regional airline they know how to work a company they have flying for a while they have a fleet with around 25 airplanes including the Beechcraft 1900D and 1 Embraer Brasilia EMB-120, those are very good airplanes they have dominican crew, they fly to Puerto Rico from HEX to SIG and SJU and from SDQ to SJU with a 727-200ADV I think, so they are NOT a new airline just guessing around, they know how to handle it.
I know they are wet leasing planes, but that doesn't mean they'll be outta here as soon as Aeromar.
Aeromar was a freighter carrier, they DID star trying with passenger they did good for a while, but there a lot differences between one and the other. Aeromar, probably didn't have the same experience and maybe tryed flying too high. They wanted go too far in a short time.
Boeing 747 from SDQ to JFK!!! Weird ain't it???
So, let's see, let's wait, let's hope the best, cuz maybe a good dominican(even if it's only the name) carrier can make the difference in a few years with the cat2.
