Looking to fly SYD LAX 7 Oct, LAX SYD 10 Oct for OWMD launch. The best prices I can find on these dates is CO for AUD$1973 ai, followed by UA for around AUD $370 more. Same flights. SYD SFO LAX & LAX SFO SYD is same price as direct, so seems better to be able to get the extra miles & segments. The CO itinerary has UA flight numbers for the outbound flights in K class. Inbound has CO flight numbers in H class. The UA itinerary has K class for outbound & Q class for inbound. I have a UA $150 Travel Certificate that has to be ticketed by 12 October. Is says treat as AB certificate. Also have UA Travel Credit Exchange Coupons for $400, with expiry 12 October Treat as Type B Voucher. They both say for travel only on UA/United Express. And non combinable / non extendible. The Type B vouchers say not valid for code share flights. Also have access to 2 SWU (thank's to Pizzaman's raffle on SMD3) I am Platinum Elite on CO (from status match) & 1P on UA. My learning curve here is very steep & I think I need some help if I'm to get this on hold / ticketed before the 5% drop in AUD yesterday catches up. Also possible further 5% drop suggested for next week. Am now also just inside 13 days before travel commences. Looking at all this, I think I have no hope of getting a cheap fare that will let me use the SWU. Not sure that I can use them on the CO itinerary as is, & don't know how to look for a fare class that will allow. On UA I clicked onto fares to be able to use Region 2 upgrades, but the screen told me they are unavailable, despite the price being an additional $400. Could be something I'm missing here. Maybe I should: : just go for the cheapest seat I can get &, be happy with the E+ seat for this trip. :Buy some other refundable ticket using the Coupons, & a different one using the Travel cert, both for flights before the expiry date, then cancel both - From browsing around I think this will extend the life of that "credit" for another 12 months? Would still need to work out how to do this & then get them to UA in SYD for ticketing. Will any refund be just a $ value to be used, or would I be locked into same routing? :And improve my user knowledge better with the SWU & use them next year. Suggestions would be appreciated. Thanks.
