My first post of the year, so Happy New Year.
So, what's the story here:
When I book a SFO - NRT ticket
1. The itinerary my travel agent sends out notes the mileage as 5164 miles
2. When I access the reservation on nwa.com, the mileage is 5131
3. When I am buckled up in the plane, the TV screen says 5109 miles
4. When the mileage credit makes it to my DL Skymiles account it is 5124
What is going on there !? I can understand #3 above - the TV on the plane is likely based on GPS data, and probably the most accurate. Why are the rest off from each other...?
On the same note, do you guys see this in your travels on other airlines? Sorry if I am bringing up something obvious to all of you. I noticed this just about last week, and verified my upcoming itinerary for this anomaly.
Thanks in advance.
