We've heard little about Avianca before this trip, not sure what to expect. But we were pleasantly surprised. All four legs of the flight were on Avianca's 787. We found service and catering out of Bogota to be much better than out from LA & Madrid. Quality of flight attendants varied greatly. Two flights out of Bogota the service were excellent, and two other flights the service left a lot to be desired. On the flight out of Madrid, one of the flight attendant even had attitude when we made a drink request. Again, meal quality varied greatly too. The flights out of Bogota the meals were good, but flight out of LA & Madrid the food was like... airplane food. The seats were comfortable, enough space for an ok sleep. The flagship lounge in Bogota is stylishly designed, but on the small side and catering and amenities limited. Avianca uses Star alliance lounge in LAX & Iberian lounge in Madrid.
