At the risk of displaying ignorance, I would like someone to confirm that L fares are eleigible for 100% miles, 50% Q credit, but Q fares earn nothing for transatlantic flights. I have a $416 L fare (web special) from SFO-LHR in December - it looks like this will get mileage credit. I always thought that L fares were the bottom of the barrel - when did Q fares get below L?
