At check-in, can we use miles for last seat availability for upgrades?

Yes, in theory

Link to thread

Probably the best “investment” I’ve done, as I was further op-up at checkin counter to J. I can’t think of a better start as OWS.

Some interesting observations: I saw the inventory of PEY dropping each day closer to the flight, but some seats are open for selection. I checked again this morning and there was no availability on J and PEY.

Just to add: I saw around 20 boarding passes printed on the table. Basically everyone in the business class queue (Silver/OWS or above) is either already on business class, or got a red light when scanning the boarding pass. A group of two queuing in front of me got upgraded from Y to PEY and took my original seat.

OneWorld Ruby - HKG to SGN - was told I had been upgraded to Business when I went to drop my bags off - I had previously completed OLCI and selected an Economy seat for my Economy ticket

Quick question: If you have both BA Silver (OWS) and CX Silver, which status will you use until boarding where you switch back to the FFP to credit miles? Or is there a difference if travelling alone? Thanks!

BA Silver - you have +1 guest, non-CX lounges and +1 pc up to two.

But what about op-up chances? I have heard somewhere that CX puts silver ahead of other OWS

A bit of a wash (see this thread's wiki)

Upgrade with Asian miles while use AA EXP FF?
 

I have a flight from Taipei to London via Hong Kong on CX. I am One World Emerald through AA EXP. No status with CX. Booking Fair class is “economy essential”, upgradable with Asian Miles.
I want to use my AA EXP number to access the lounge, but also use Asian Miles to upgrade to premium economy or business.
What are my options?
Thank you.

Put in your Asia Miles number first to process the upgrade (if upgrade space available). Once ticket reissued, put your AAdvantage number back in.

I just learned that CX won’t award AA miles on most economy fare, even I choose Flex fare. The H fare which awards AA miles cost almost the same as premium economy.
Here is my dilemma : I plan to purchase CX economy and upgrade with miles. If I use my Asian miles number, I will earn miles on CX. Will I have access to the first class lounge with my One World Emerald from AA? ( show my status on AA app?).
The other option is to get the upgrade with Asia Miles and change it back to AA. I have access to the Pier First class but I won’t earn any miles on my flight.
Hope there is a way I can get CX or AA miles and access to first class lounge.

Put in CX number for check in and show AA digital card at Pier F reception.

Anyone recently scored a successful mileage upgrade from PEY to J on MXP or CDG route? Trying to realistically gauge my chances.

I have a dilemma of booking a HKG-Europe roundtrip on EK in J for $25k HKD; or go with CX PEY R fare for $29k HKD. The EK option is attractive since it guarantees I'll fly J, the drawback is obviously the connection at DXB of about 4 hours. CX option is best for schedule but I'm absolutely sure I'll be sweating until the last second for the upgrade even if it does come through.

A third option is booking QR J via Iberia for about $31k HKD with a connection via DOH (and fly Cirrus J on CX's ex-77W birds now leased to QR for the legs to/from DOH). However I'm not too keen on a midnight departure ex-HKG and afternoon arrival at CDG.

MAD-HKG-PVG rt, was booked in E and the upgrade bid was 1013eur for MAD-HKG, called in and they offered 391eur total to upgrade to I class for MAD-HKG-PVG altogether....inventory is I9 for both flights at <48hrs before departure.
Does the call center's upgrade price adjust (downwards) as inventory remain high and time to departure decreases?
If flight is stll I9 at check-in at MAD would the counter offer even an even lower price?

Pretty sure the call centre just quoted you half of the round-trip difference between E class and I class plus change fee.
(1591-1043)/2+150=424EUR, but maybe when you bought the E class ticket, it was a bit higher.
