Nonstop Airlines from NYC (JFK, LGA, EWR)-MCO:
New York-JFK(John F. Kennedy International Airport) in Queens, NY about 30 minutes to 1 hour from Midtown Manhattan:
-American-$25/bag, not a bad choice from JFK, but the plane was not in perfect condition and the baggage delivery at your destination was slow. The service and seats were OK and we got to Orlando safely and on time!
-Delta-$23/bag (online)/$25/bag, one of the better choices on the LGA/JFK-MCO. We have always had excellent inflight service, decent seats, free snacks and drinks, and quick baggage delivery. Depending on the type of plane, you may have inflight entertainment.
