I booked one of the special WBC "Z" fares to Europe over Thanksgiving. These fares are only valid out of certain, mainly east coast, points of origin. I could not book this fare from my midwest point of origin and so booked a W fare to link to an eastcoast departure city that had this Z fare availability.

So, I now have two separate itins with separate confirmation numbers. One is W class from A to B and return 10 days later. The other is F & Z class from B to C stateside, and to D to E in Europe with return 10 days later. The Z itin is nested within the W itin.

The Z was booked online and the W was booked with the GE line, CSR being the only way to redeem the ECV that provides a fee RT in W.

Will I encounter problems with this due to rules about nested itineraries? Will I be able to check luggage all the way from A to E? I can call NW and ask but wanted to get someone's opinion before I call attention to my situation.
