so i learned the ANA tool, aeroplan search, CO search limitations, Award Nexus tool I have the trip booked YYZ-CDG-BKK-DPS dec 28, DPS-BKK stopover jan 11, BKK-LAX-YYZ jan 13 all in F or C award from CO (190k miles/pas for 2 pas) on mostly TG and AC i love YYZ for international travel since i am in BUF new F opened up YYZ-IAD-LHR-BKK-DPS on a later date that could be nice (jan 1) since the current itinerary is a bit long and i would like to shorten it a bit (so as to miss less work). there is hardly any availability on return awards from Asia to US which is super annoying... The YYZ-IAD seems almost silly to take...I could easily do direct BUF-IAD which would either make it open jaw (allowed one per CO award i believe), and therefore reticketing and rchange fees ~$300. can't skip the first leg of the itinerary on an award right? any advice to avoid the change fees? has anyone had luck with their travel insurance or Chase CO Onepass plus trip coverage covering these things like this?
