We just returned from Bolivia back to Miami on American Airlines flight 922. All I have to say is that the service has gone down below any expectations. The flight was late by more than 1 hour with no explanation. The ground tellers are rude and arrogant. The plan was an old B-757-200 that has the seats so old that you can fell the metal underneath the cushions. The in-flight service was mediocre. The food was served late and the meal was simple.
I would not complain but the tickets were about 1200 per person (round trip). I have used American for similar flights but it gets worse every time. If you can avoid this specific flight, do it! Go TACA, LAN, AVIANCA or Aerosur and maybe you will have a better chance for a good story.
I would hope to see this service improve since they are the only US airline flight to Bolivia. Perhaps it's not the nicest place on earth but compared to the services to SCL, EZE, GRU and LIM, the services to LPB and VVI are just poor and sometimes offensive. The smaller and older B757's are just not comfortable for a 7-hour flight.
