My roommate is supposed to fly SBA (dep. 4:56pm)-LAX-TUS (arr. 9:25pm) today, but the incoming flight is delayed due to broken aircraft. He won't make a connection at LAX.
UA put him on US SBA-PHX (arr. 9:47pm) direct flight but there is no flight to TUS from PHX tonight, so he will need to rent a car and drive to Tucson tonight. This is award tickets by the way.
What is compensation due in his case?
