KLM GUC Questions
I've read through a lot of recent threads here on using GUCs on KLM but can't find the answers to a few questions:
1) KLM flight shows Z0, so I know it won't clear today. Will the GUC change to an airport upgrade list? The flight is AMS-SFO.
2) Do I need to book the flight under a DL or KLM flight number? I'm looking to piece together a 4 leg itinerary, SFO-JFK-DUB-AMS-SFO. Legs 1 & 2 are DL numbers and DL operated. Leg 3 is KLM numbered and KLM operated. Leg 4 is KLM operated, but I can currently book as either KLM or DL flight numbers. I read that if there is KLM Z showing on EF, then DL will reissue as a KLM number, so I thought perhaps I'd do that, but then wondered if it would force a non-006 ticket stock. Wanted to be sure before I hit the OK button and could not find a distinction in the rules.
Thanks for any insight!
