I checked on all of those flights, the only other one that looked like it would work out for me was the Lufthansa flight which is ideal since it arrived into Vancouver earliest and also my flight over to Paris would arrive earlier than I've seen any other carrier get in. The fare is ok right now too. I'm still waiting on my boss to give the final goahead to book these right now, so I decided to book the Delta fare since it is refundable within 24 hours. Lufthansa doesn't say on their website and their reservations desk couldn't pull up the same itinerary (I guess they don't have access to all partner airline flights that can show up on the website). The agent told me that if I called immediately after booking online he could check on the rules and refund it right away if it didn't have a cancellation period. That seemed a bit too risky to me to rely on his word there, so I'll just hope the fare hasn't changed before I can get the trip confirmed tomorrow.

Thanks for all the great info everyone! ^^^

EDIT - We use AXIOM and are supposed to book all travel through it. It does give multi city options for this route, but it's quite expensive. No one really knows if I book it myself, so I often do...I suppose I may call them to see if they can get the lufthansa flight tomorrow, best not to tempt fate if possible
