I was just doing a search and Continental's EWR-HKG flight is scheduled as 15 hours and 40 minutes. The return leg is scheduled as 15 hours and 45 minutes. Why is it longer going eastbound? Also, how long is the actual flying time on these flights? On the UA ORD-HKG and HKG-ORD flights? Thanks!

The answer is simple and if you went into the schedules to look at most other flights, you'd find scheduled time different between flights at different times of day, even the same flight number on different days of the week, or routes on the opposite direction. The airlines pad the schedules. Congestion at Newark or Hong Kong is at different levels at different times of the day. Taxi times may be extended on the return due to it being in the midst of a bank of flights, or something along those lines. As for larger discrepancies, prevailing winds aloft often cause differences in flying time westbound versus eastbound.

Although I'm not speaking from personal experience, I would imagine that eastbound would almost always be quicker in the air due to tail winds on that route. I've been on a number of NRT-JFK flights and they have always been at least an hour quicker in the air than in the opposite direction, going to NRT. But I wonder if, maybe, the fact that the flight is almost over the top of the earth means that tail/headwinds have less of an effect? Just a possibility I thought of.

Good point Cba. Continental routinely pads its schedule on flights leaving Newark due to chronic congestion there and limited taxi way space. The problem has abated somewhat since 9/11, when airlines cut their schedules. Nevertheless, flights out of EWR are usually timed to be longer (10 to 25 mins) than their return legs. For example, EWR-BOS is typically listed as 1h25 mins but the actual air time is 39-45 minutes.
As for why HKG-EWR is longer. Not sure. But is five minutes all that important on a 15H + flight?
