I noticed for a particular round-trip that the portion from the east coast to the west was scheduled to take over an hour longer than the return trip. I initially thought this was a mistake due to time zone or daylight-savings time oddities, but that does not appear to be the case.
I know there are a number of variables that can affect flight time (type of jet, winds, even potentially rotation of the Earth itself), so I was wondering if this sort of thing is typical. This particular instance happens to use the same model plane for both trips and is non-stop, so most factors seem to be controlled for aside from east-west vs. west-east. Is the longer flight a good candidate to arrive early (or is the shorter flight a good candidate to arrive late)?
Edit: I recognize from this question that winds are likely to be the dominant factor, but that still does not answer my question. I'm specifically asking about the USA and I don't know what sorts of winds are typical (or whether or not it depends largely on southwest vs. northwest, etc.).
