outbound to co, inbound to nw
 

has anyone ever had sucess crediting the 2 legs to diff programs?

example, i buy a cle ord on co

credit cle-ord to co
credit ord-cle to nw

it is no problem. Just have your CO# on it for the flight down and when you check in @ the airport have them change it to your WP#.

I did this with my son's account once. Roundtrip itinerary was 1,000 total miles but he needed 500 miles in two different programs to top off his accounts. As long as you have them change it at check-in (do not use kiosk check in), verify the number on your boarding pass, you'll be fine.

Why not on kiosk? I think even for kiosk check-in you have the option to change the frequent flyer number.

Hmmm....maybe youre right...I dont recall. Try it and let us know!

Yes, I have done this. As you have been advised by other folks, make sure to change your freq flyer number between the differenet legs of the journey (at the changeover location).

I've got a trip this coming weekend that I'm flying BWI-DTW-DAY-DTW-BWI on NW metal, same day return. I'll have enough EQMs to get gold on NW this year by years end, so I'm not really concerned about the EQMs. Is there anyway I can do a FF switch? My DTW-DAY-DTW are on RJ's, so I won't get an upgrade & the extra 500 banked miles in NW don't really matter all that much to me, but I could use them in CO. I would like to fly BWI-DTW & DTW-BWI in F though.

Has anyone ever tried switch the FF number mid-itinerary & successfully been able to do it? If so, how did that work in terms of posting the miles?

Worse case scenario, I could just enter in my CO account number & fly Y the entire way (I'm confident I'll get the elite upgrade if I earn on NW as it's Saturday travel & the planes aren't super filled with elites).

Thanks!

I did this once on NW at the connecting flight gate, but it resulted in my already flown flight being credited to the newly given FF#. Gate agent seemed rather peeved to accomodate my request, and I made it clear that I wanted to change only the connecting flight and have the original flight credited as per the boarding pass. Was a big hassle to get credited the way I wanted once I discovered the error.

If the F upgrade went through & I was already in DTW, I guess it wouldn't matter that much then as I don't really need the EQMs.

Why not wait: leave out the numbers altogether and send in the boarding passes to the programs you want to credit the flights to? Shouldn't that be the safe way to go?

Would that work? I imagine that since it's NW metal, it would work for the CO miles, but would NW question where the rest of my segments were?
