Recently flew PRG-CDG on Air France. Could not give our SkyMiles #s before date of travel as tickets were booked in bulk by my gf's company as part of an award trip. Checkin was a zoo and I forgot to add the account #s then too. Figured I would just do it when I got home, as this has worked getting AA miles for oneWorld flights.
However, delta.com partners page says:
For air travel: Provide your SkyMiles number at time of booking or check-in for each flight.
and the Request Mileage Credit form only lets you choose Delta as the operating airline.
Is there some alternative means of claiming credit, or am I s.o.l.?
