It was a
DOT ruling. In general ‘obvious’ unilateral mistakes cannot be enforced in contract law but let us not go down that rabbit hole.

Yet I phoned on Tuesday and got it ticketed at the pre price rise fare.
Normally once a PNR has been fare-quoted the quote will survive changes to the fare rate and even the unscheduled removal of the fare from the tariff. If the fare has a scheduled expiry then the PNR's TTL (ticketing time limit) will be set to expire together with the fare. Otherwise the TTL is set to the most restrictive ticketing condition implied by any fare on the PNR. For BA fares on the public tariff that is usually three days.
Probably in this case AA actively requoted the ex-MPM itineraries knowing that the price had materially changed.
