Although I was assured twice by United that Avianca was their travel partner and that I would not be charged for my bags at LAX and even though my bags were checked through to San Salvador, we were charged $275 for our bags before being allowed to board. We have had a family tragedy while here and haven't had the time to call United yet. The gate attendant and her supervisor were completely unsympathetic and told me they didn't care what United said refused to at least charge us the online fee instead of the airport fee. Worst experience I have ever had with an airline.
