I would like information on my baggage allowance for an itinerary booked through United Airlines with segments on Air New Zealand.
UA PNR xxxxx
NZ PNR xxxxx
Routing is:
MSP-ORD on UA
ORD-YVR on UA
YVR-AKL-NAN on NZ
*Stopover in NAN
NAN-AKL-SYD on NZ
*Destination is SYD
SYD-SFO-DEN-MSP on UA
My understanding per US DOT rule 14 CFR 399.87 that my baggage allowance for the entire trip is governed by the operating carrier of the first segment of my journey, which is United Airlines.
My concern is the baggage allowance on the segment from NAN-AKL (NZ755) on Friday November 23. I will likely have 3 bags to check, all under 50 pounds in weight.
Per US DOT rule 14 CFR 399.8 OR because I am connecting to an Air New Zealand flight in business class for the AKL-SYD segment: will I be able to check 3 bags without a baggage fee when I check-in for my flight NAN-AKL?
Thanks in advance for this clarification of the baggage fees I will pay.
