Pilot contract will probably prohibit hub-hub barbiejets.

What do the rate of fuel stops yesterday, or last week, or last month or 6 months go have to do with the rate that will exist next week, or next month?
Same reason they list on time performance rates. They're not causative of future delays, but they're indicative.

The ghetto bird 763 range isn't much longer than the winglet'd 752 range.

1) You're the first person to mention rate; the article never says rate. The "amount of fuel burned" (their actual words) is a quantity, not a rate. Fuel burn rate would be a rate.

2) Increasing fuel burn rate (and airspeed) isn't uncommon when flying into a headwind to minimize the impact. 100kts on the nose is less impactful in terms of time if you're making 550 through the air instead of 450. I don't know if United is doing this.

Do they publish the on time departure rate or the on time arrival rate?
