For a multi-city TPAC that involves segments on UA, NH, and AC. I see the "Book with United" option on Google Flights but it isn't clickable. When I search using the same parameters on UA.com, the outbound flight is much more expensive, and I don't even see the AC inbound as an option. If I call UA and feed them the flight numbers would they be able to ticket it for me on 016 using the Google Flights price? We are talking thousands of dollars (J ticket) so this means a lot!
