As Polaris seats have been rolled out, United has the following counts of Business Class seats across its fleet:
- 60 on 777-300ER, 50 on retrofitted 777-200 planes.
- 48 on 787-9, 36 on 787-8, (soon to be) 44 on the 787-10
- 30 on their 767's
- 28 on Internationally Configured 757-200s.

Meanwhile, Delta has only:
- 32 DeltaOne suites on their A350
- 28 seats (soon to be DeltaOne) on their 777-200s
- 34 seats on their A330s
- ranging from 26 to 40 seats on 767s

And American has:
- 52 Business Class seats (and 8 First Class)
- ranging from 37 to 45 seats on their 777-200s
- 28 seats on their 787-8s, and 30 on their 787-9s
- 20 seats on their A330-200s, and 28 on their A330-300s
- 28 seats on their 767s

For no aircraft (except the 767 vs. Delta) does United have fewer Business Class seats, and for some (like the 787s vs American, or 777 vs Delta), they have substantially more seats. Anyone have any insight into what their strategy for this is? On my recent United flights (mostly to Asia), I've noticed that they sell out 80%+ of the Business Class cabin, but I don't notice that their fares are substantially cheaper than either Delta's or American's. Are their hubs just better situated for Business travel, SFO in particular (with the explosion of tech companies)?
Thought this could be an interesting discussion
