where som changes made to search on ITA? what am I missing?
Technically, the commas are an "or," so you're telling ITA: one single flight on United or United or United. (Not sure if the spaces after the commas affect the syntax, as I always do something like "UA,DL,AA"). The correct syntax is without a comma, as
KVS indicates.
