Can someone shed some light on why airlines run "unbalanced" schedules between a pair of cities? For example, United flies 3x daily from SFO
(departures ~ 9:00, 13:00 & 23:00), but only 2x daily from EWR
(departures ~ 6:30 & 18:00). Similar sized aircrafts (mostly A319s through mid-Feb, then mostly 757s after that) are used in both directions, so it is not like they are making up the imbalance in seats by running larger aircraft westbound. It seems like a mid-day/early afternoon departure from EWR
that would arrive in SFO
around 16:00 to allow for connections to Hawaii or other locations up & down the pacific coast would be useful. By the way, they make up this difference by running EWR
8x daily while ORD
is only 7x daily.
