Time difference between DL2907 and DL 2908


#1

Can someone explain why the flight from KIND - KLAX on DL2907 is about 5 hours long and the return KLAX-KIND on DL2908 is just over 3 hours long? I just had this flight and it didn’t make sense.

I know the earth rotates and this might have something to do with it, but it rotates E to W so you would think that the 2907 flight would be shorter. What am I missing?

Two guesses, time zone changes and wind speeds. Going from IND-LAX, you cross two time zones, losing two hours in the process. Winds aloft also typically run west to east, making westbound trips longer.


#3

3h42 min for 2908 vs 4h54min for 2907. Different is only 1h12min and it’s due to winds.

100kts on the nose vs the tail can mean 450kts vs 650kts.


#4

Timezones have no impact on time en route.


#5

I was just thinking if you saw the flight leave at 1PM, and arrive at 5 PM, without paying attention to which time zone. I didn’t look up the flights in question.
