The maximum is $300. It's been a lot tougher this summer to get takers for that. Especially since flights are so full, the next option is usually out of Boston or the following day.
Do you also have directives to not book OAL?
United was $400 a year ago, flat. 2 years ago for an overnight domestic it was $600. 2 years ago I could've gotten 2 transcons for $600, today I'd get a little more than 1 for that, and the value is less than half of what they offered a little while ago.
