I had the oppertunity in flying Atlantic Air in Managua to the Atlantic Coast of Nicaragua. They have Cabin Class service, this means you are not crammed into a small plane with no head room or space to move about. Very good On time schedules and good service onboard, yes they feed you!
They also offer all Central American countries.

Give them a call or drop them an e-mail.If you have ever flown with them, I would like to know how you were treated and what it would take to make the airline suit you better.
I will make sure the Owners get your responces. Good or bad ones.
