A friend of mine flying in J on AA LAX-JFK (with no status) was just turned down from the oneworld business lounge at LAX, despite the rules:
Departing in First or Business on AA on a domestic flight three class flight or over five hours in length (currently, LAX-JFK and domestic F LAX-BOS).
They were told:
"We received a new policy yesterday via email stating that you're ineligible on a domestic flight. This new policy is not published anywhere online."
Lounge staff were adamant, despite my friend asking for a second opinion. Very frustrating. Anyone else with experience like this?
