I am and have been a American airlines EP for years. I received an offer to status match on United to Premier 1K. I am sure I missed it somewhere on the site but i can't seem to figure out the upgrade policy for Premier 1K status. Can anyone point me to the right link for that?

Thanks

Now 7 Million and counting. 1K

Sure. As a 1K, you'd have theoretical access to complimentary upgrades (CPUs) on eligible routes (domestic and short-haul international, excluding Hawaii beyond California or EWR/LAX-SFO) as early as 96 hours prior to departure. You'd also get access to PlusPoints for confirmable upgrades as early as booking (similar to SWUs).

Depending upon your location and flight patterns, CPU clearance rates range from 0 to ~80%. PlusPoint upgrades range from 0 to 100% if you're extremely flexible -- but upgrade inventory has become increasingly scarce recently. If you're traveling Monday to Thursday, LAX to EWR or vv, your chances of upgrade are near zero. If you're traveling DFW-LAX-FAT midweek, you may get CPUs on a semi-regular basis.

As a status match / challenge you will not receive any PlusPoints initially. Once you meet the conditions of the match will receive a partial set and once you meet the normal requirements, you will receive a full set.

What routes are you thinking about?

Best to understand, 1K is not top tier UA, GS is and the UA GS pool is believed to be larger than the CK pool on AA.

Core priority process is below

So at Delta as a Diamond I got upgraded 90% of the time. That is not the case with UA as a 1K. They have a done of Global Service who come first. At Delta I never really came across more than one Delta 360 pax on a flight. UA is very different. Can’t speak to AA and EP vs Concierge Key pax. But 1K is really not the top of the heap at UA

Even GS is not top tier.

Of course, the top tier CCs are buying J, so upgrades are not an issue for them

Aside from upgrades, you had mentioned you are 7 MM with AA. UA counts miles differently for lifetime purposes.

AA used to count credit card spend as accumulation of MM. Upon moving to loyalty points, credit card spends no longer count toward MM. It's now all about BIS, butt-in-seat, similar to UA. AA, however, still counts partner flights. UA you have to earn it one mile at a time for lifetime miles, no bonus, no credit card, no partner earning.

For what it's worth, when I was simultaneously Exec Plat on AA and 1K on UA (for 3 years IIRC), I had a much higher domestic/complimentary upgrade percentage on AA than UA. I sense that's still the case based on input from others. Just a forewarning.

I absolutely would not switch from AA to UA for upgrades. Your percentage is going to go down (I say this as a former EXP 2019-22 and now 12 year consecutive 1K).

There are other reasons to switch, including particularly better IT. But the main reasons would be that you're either moving to a UA hub or will be flying frequently to a destination that UA serves much better than AA.

It is in my case as well. I also have a higher complimentary upgrade percentage on AS than UA, thanks to the AA/AS partnership.

I agree with other responses. I was an AA CK for six years and before and after that 1K for another dozen years. Even being ORD based taking elite-heavy flights I rarely missed an upgrade domestically and I was always able to upgrade my ORD/NRT flights (about six to eight times a year) from J to F using SWUs at booking. Back when AA was running three class 777s TPAC. I was matched to GS one year without asking when UA tried to pick off AA CKs during the merger chaos. I tried to fly UA a few times but could not get any global upgrades to clear anywhere near booking and I never did get a CPU to clear before 24 hours out even on elite-light flights. I just burned my regional upgrades and wrote off UA.

After retiring, most of my flying is between homes at ORD and RSW and UA has better frequency and pricing than AA. I buy P fares so I don't worry about upgrades. However, I have seen numerous times GS pax sitting in the back and they have top priority for upgrades. UA seems to have far more 1Ks than AA has EXPLs that you would be competing with for upgrades and most end up in the back on my flights. And I agree that there seem to be more GS at UA than there are CK at AA. So I agree with others who have posted that if the main reason for moving to UA is CPUs, you will likely be disappointed. But coming from DFW, where AA dominates, who knows.
