= 1.55 for each leg of your trip on United
For example, yesterday, I flew PHL to IAD, then IAD to SFO:
PHL to IAD is 0.75 hour flight time.
1.25 hour layover.
IAD to SF) is 6 hours flight time.
Scheduled travel time = 8 hours.
Using the United Travel Delay Coefficient:
PHL to IAD = 0.75 x 1.55 = 1.16 hours
1.25 hour layover.
IAD to SFO = 6 x 1.55 = 9.3
Actual travel time = 12.15 hours
Nice work ignoring the cargo loading plan at IAD.
