Trust & methodology
How TopTier estimates your Global Services outlook
United doesn't publish its Global Services invitation criteria. TopTier estimates your odds from the travel signals most closely tied to reported invitations. Here's what we look at, where our information comes from, and where the estimate has limits.

Three levels of information
- Official United rule
What United publishes: Premier tier thresholds, PQP and PQF rules, and the fact that Global Services is invitation-only.
- Publicly reported
What flyers report: the travel profiles of members who were and weren't invited.
- TopTier estimate
What TopTier infers: a probability built from those reports and applied to your own travel. It is always labeled as an estimate.
Signals we analyze
Paid United-operated spend
PQP from flights United and United Express operate, counted separately from partner, award and credit-card PQP.
Premium cabin and long-haul mix
How much of your revenue comes from Polaris, first and international flying.
Consistency and history
Prior Global Services standing and spending that stays steady year to year.
Trajectory and context
Trips you've booked but not flown yet, plus home-market context.
Cost per mile (CPM)
What you effectively pay per mile flown — higher-yield tickets carry more weight than deep-discount fares.
Spend per PQF
How much revenue each qualifying segment represents, separating long-haul premium flyers from high-frequency short hops.
Current year status
The Premier tier you hold today, and whether you're on track to maintain or exceed it.
Home airport
Your home market and hub context, which shapes how your travel compares to other flyers United sees.
This is an independently built AI Machine Learning Model that uses the factors above. We don't publish our exact model weights. They are proprietary, and publishing them would suggest a precision that nobody outside United actually has.
Independence, privacy and data handling
- Toptier Aero is independent and not affiliated with or endorsed by United Airlines.
- We never ask for your United MileagePlus account or password.
- Your travel data is used only for your projections, monitoring and alerts. It is never sold.
- Data is stored with row-level access controls, so each account can see only its own trips.
