Distance Out vs back

Seems like these two numbers to should be the same. Looking at several mileage calculation sites I get between 731 and 733. Other then some earned points it doesn't matter but I am having a hard time understanding how the Delta system can list different distances based on direction. Thanks for letting vent my first world problems....

Maybe the airport is moving over the weekend?

Maybe there's an earthquake planned for next weekend.

Longtime issue. They apparently pull the mileage in the flight info section from a separate database than what's used to credit the flights. The mileage calculator shows the correct number in both directions (733 miles).

Discrepancy between miles flown and base miles which calculate MQM's posted

How does that make sense of the OP's question? The outbound and return are different. He even circled the problem.

Yeah, I get it. Just pointing out that the flight info mileage information has long had consistency issues and the above is one more example of it. Fortunately, they do not seem to use this database when crediting MQM's for flights.

Maybe Al Capone is on the return flight and, umm, "convinced" DL to give him extra miles for it?

I just noticed the same thing on MY ATL LHR flights, out on Delta return is Virgin, unsure if it is the difference in airlines or the routes they use. I will look on some of my history since I do this route semi frequently.

Thanks all for the replys. I even did a search of the topic thinking this was not new but missed that thread. I guess next time my checked bag is 51 pounds I’ll tell the agent it’s “a know issue” and we all have them.

Could it have something to do with the actual route, I am no pilot but if they are scheduled to fly a different route it could add more miles, I mean westbound flights are longer time wise, could they take a physically longer route to make up some time? No different than I take a longer drive to the airport so I can drive 70mph vs a shorter distance at 45mph?

Wouldn't it be nice to get credit for actual miles the flight plan took! If you had to avoid weather, got put in a holding pattern or just got routed the long way. The first points program that can offer that would get my attention.

Ha- that would be nice, but as someone mentioned before milage earn is not the same as mileage flown. I figured, like time, they are showing the planned miles which is not related to what you earn. I thought they changed the mileage earned to be based on fare price anyway?

[JOKE] Eastbound versus westbound? Well, for westbound flights, don't planes just go up in the sky and wait for the earth to rotate so that where they want to land is right underneath the aircraft? Conversely, most eastbound flights race to chase the earth as it rotates and they can only land after they more that catch up. So of course eastbound flights should earn more miles. [/JOKE]

If a plane was trying to takeoff on a treadmill going west that was programmed to match the speed of the wheels versus a treadmill with the same programming but going east, would it make a difference in whether the plane is able to takeoff?

It would depend on whether the treadmill is turning clockwise or counterclockwise.

However, taking off from a treadmill requires either some additional dimensions or that the treadmill be a Mbius strip.
