I highly suspect that there's still no way AA could prove,
well after the fact, what the available fare was for flight 1234 PHL-DFW
at the exact instant that I bought my hypothetical PHL-AUS hidden city itinerary.
Fare class availability could have been dramatically different between 7am and 3pm on the same booking date. Even if no new fares were filed or removed.
