Intruder, between you, me and the fence post I agree with you 100% that 1+3 is not a double crew, nor was it the intent of the FAA FAR's, but you know the power of lobbying and $$; it has unfortunately become industry standard in the USA. Delta is thus far the only hold out...we are facing it too, in the contract that we are voting on. As for the duty day issue, for us it is a contractual one that would allow a double crew to run longer than a augmented or as some call it a heavy crew. That is a different can of worms!
