This is my first post. I am looking to find the best first class service from DCA/IAD/BWI to CUN. When we were married we never had a honeymoon and for celebrating our 10 year anniversary I want to take my wife to a romantic stay in Riviera Maya, Mexico to an all-inclusive. I want the flight to be a nice part of the experience. I am in no way a frequent flyer and need help in choosing the right airline. Living in DC, I can go to any of the 3 airports to fly out of. All help/suggestions are appreciated.
