Booking this flight with United was cheaper than Expedia that was for sure a surprise, but the service was a better than expected. Last time I used United to fly out of the country when I went to Brazil, the flight attendants were a bit rude when I asked for water, as well help on direction when getting on and off the plane.
The only reason I booked my recent last flight to Panama City, Panama with United was because they were the cheapest price. But the outcome surprised me, and I am glad for it.
The flight at first was delayed a little, which upset me, but still left that same day. The flight crew was helpful, and friendly. Very accommodating the staff was to me. They didn't lose my luggage either which is the first time that's happened, and I was glad it didn't after previous experiences of them losing my luggage. They were no more economy seats on one flight so they upgraded me to economy plus free of charge. which was great.
The only issue I had was that like most international flights, they wasn't any free alcoholic beverages given free like most previous international flights.
