just curious, anybody ever fly an airline that gives you EQM on other airlines with 2 purchased tix so as to double your awards while saving you some time?

One example i been looking at was good deals on AlaskaAir flights from SEA to MIA. You could book 2 of these tix at about $350 a ticket. Put one of the freq flyer #'s as your AA FFN and the other as your NWA FFN. For $700, you can earn 5400 miles on both NWA and AA with only 1 milage run.

Is this a good use of your milage run time?

sounds like a double dip to me, and you may get nothing! If you have had success with this, the last place to post it would be in such a public place...

BUT thanks for the tip! Not that I will try it, but it could work!

Anyway, I have had success with things like this involving two FF accts on one flight when I flew overseas when DL and UAl were partners. I got them to credit all the domestic portions to DL and all the international to UAL. This, they could do... Maybe this can still happen and since Alaska is a third partner in the AA/NWA thing, it may be possible to swing something like that here. They are domestic but you may have some luck. If you booked both legs as separate locators or sep itins, then I am certain it can be done. I dont see why not.

Another time we flew America West to Reno when they were partners with CO. Got the CO miles on the way to Reno but when we were going home we experienced a huge delay and they sent us back on an available AA flight. A letter of complaint to America West concerning my delay had in it a request to get the CO miles because that was what I was after when I took the trip. CO gave me the miles and yet, I had already earned AA miles as well. They said I could keep them too.

If you flirt with the person at the check in desk, a lot of good can come of this sort of stuff as well.

Unless I misunderstand the original post, you want to buy two tickets on the same flight, one with each FF program, and get credit for both when you fly.

Since you only board once and therefore they only collect one boarding pass from you, wouldn't the other one be recorded as a "no show" and earn no credit?

You could always say you booked the second seat for comfort, for your cello, or whatever, and check in with both. Might work that way. I doubt a gate agent or electronic boarding pass reader would care if the FF numbers on the two BPs are different.

In that case, to answer the original question: if a flight is worth it as a mileage run for one program, it should be even more worth it with two programs, since the ancillary costs such as airport parking or travel and meals en route don't go up. However, this presumes that (a) you value the miles in both programs about the same, which would not be the case for many people here who value miles in their primary programs much more than any others, and (b) flight-related bonuses, which often justify a MR through double miles and so on, are good enough in the secondary program to justify the cost of the second ticket.

i suspect that you would have trouble checking in for 2 seats....there have been discussions on this in the past which included comments that a heavy person who buys 2 seats for comfort can only get ff mi etc for 1.

This has been discussed in other threads, to which future thoughts would be profitably posted, if we want to have all the ideas on this topic collected in a single place.

See, e.g., Double Mileage Run: buying two tickets for a single flight
