Flew from Boston to Terceira and back as part of an Azores Getaways package. The flight left Terminal E in Boston and was an overnight flight. The SATA fleet on this flight consists of Airbus A310 airplanes which seat about 220 passengers. The planes were made between 1983 and 1998, with the bulk being made between '83 and '92, so the planes are not new. The inside of the planes were very clean and well staffed. The stewards/stewardesses were all very professional and helpful.
About 1 hour into the flight a meal service was provided, which was remarkably good for airline food. Also wine and beer were complimentary. The seats were fine, and even though the airplane was on the older side, it appeared to be very well maintained.
The crew passed on headphones on one of the legs (maybe both) for use on the system - some type of movie was also shown on the old CRT screens. I did not use the inflight entertainment, so I cannot give an accurate review - stuck with a paperback and some earbuds and my phone, but it was definitely outdated - occasionally the screen would show the location of the plane en route, along with altitude, time until arrival, and flight speed.
The plane unloads from the front and back on two wheel in ramps in Terceira, where you are shuttled to the terminal for processing through customs, which was uneventful. All in all, I would not hesitate to fly on SATA again.
