    I'm trying to book a trip in December, and want to maximize MQMs earned. On the return trip to EU (SEA-AMS) I've found a route through ATL (few hours layover). My calculations say that will give me ~1000 MQMs extra, but delta.com's calculations on the confirmation page seem to ignore the extra 1000 miles as if I flew SEA-AMS non stop.

    Anyone with experience with that who can explain me if Delta only count miles based on the "shortest possible available route"?

    Thanks! :)

    Try searching/booking by segment, aka 'multi city'.

    That is the solution I have used. Caution: sometimes the price changes, maybe up, maybe down, depending on leg pricing. Often connections through ATL are more expensive that way but YMMV. I am doing that myself now with some pricing changing higher, some lower.

    That was what I did - I selected the exact route (CPH-AMS-ATL-SEA-ATL-AMS-CPH) that I had calculated to 14078 MQMs on http://www.milecalc.com
    But delta.com says 13080 MQMs? :)

    I bet somewhere in there you have the same "Flight Number" even tho you are stopping.

    Delta counts 'direct' flights, one that may have stops and maybe change of guage too, as 'nonstop' so award 'point to point great circle routing' miles. The only solution is to ensure that each flight number is different.

    I can get close to DL's number by dropping a "stop" on milecalc, so I bet that this is the case.

    Ok, so what does that mean? How will they calculate the actual miles I get after the trip? Will I get ~13,000 or ~14,000 MQMs? :)

    If two consecutive flights carry the same flight number, regardless of whether there's an aircraft change, your MQMs earned will equal the nonstop. You will not get the extra thousand miles, and booking these flights as separate segments using multi city will not help MQMs (but it could have other advantages for seating and upgrades).

    Example:
    CPH-AMS-ATL (both segments have different flight numbers) 4,900 miles
    CPH-AMS-ATL (both segments have the same flight number) 4,603 miles

    I don't think it's the case here. E.g.:

    CPH-AMS-ATL:
    DL9611-DL9374

    ATL-SFO:
    DL1355

    SFO-ATL:
    DL1866

    ATL-AMS-CPH:
    DL50-DL9360

    Delta's calculated total: 13580
    All other online calculation tools: 14078

    Please always be prepared that online Great Circle mappers and DL, or any other airline, use slightly different tools. We, as cynics, probably see that the airline tools are almost always a few miles shorter than our online tools indicate. It is part of our life.:(

    Very true. We have seen city pairs that have grown closer together with the great RJ/FC announcement from years past.

    Isn't it amazing how the earth is shaped differently depending on the perspective of the measurer? Airlines probably are not fans of Galileo, unless they are pricing the paid tickets rather than the awards.:rolleyes:

    All these conspiracy theories! Get real. It's simply continental drift and earth shrinkage from all the crap we've left in space. ;)

    What's really interesting is that the site is giving you the wrong mileage for both the SFO-ATL legs. It posts as 2134-at least the last time I flew that leg. If you go to DL.com, pick any ATL-SFO from the options for an itinerary and click on the flight number--it will show you the mileage--and it shows 2134 currently. Gotta love DL.com :rolleyes:.

    Quick hide this post as the wizards at DL.IT will spot it and correct enhance it.

    Haha - that's even more funny!
    I did as you suggested and got the following numbers:

    CPH - AMS 500 (395)
    AMS - ATL 4387
    ATL - SFO 2134
    SFO - ATL 2134
    ATL - AMS 4387
    AMS - CPH 500 (395)

    Total: 14042 miles

    But on the trip summary page it still says 13580 :confused:

    Perhaps you should resort to buying the last few MQM's to get the numbers you want/need. Good luck -
    On second thought - do they even sell MQM's...
    I long for the old days when a mile was worth a mile and a half!

    That is better than mine today. On my MR on the weekend everything has "posted" but says the fares were "ineligible" so zero accrual on miles or MQM. Since it had "posted" I called the Diamond desk who informed me that there was a "systems glitch" that was "supposed to have been fixed last night" but instead made the problem worse, so DL IT is working with audit to fix the entire problem. She said DL IT said it would be fixed in 24 hr, but she said "I would not expect it to be done for several days because there is a huge backlog of manual corrections to do."

    One would think that the mileage for a pair of routes would be fixed database not to be messed with. A sort of read-only table :)

    the fix on mine made new mistakes. This is a bit improbable, I would think they'd not mess with the formula too, but...

    About 500 MQMs is a big difference for one RT.

    Are you sure that your fare codes all earn 100% MQMs on the KLM operated segments? Could you even have a segment that's operated by a KLM partner that isn't a member of SkyTeam?

    Yes, the only segments where I haven't flown the exact DL flights before is the ATL-SFO and SFO-ATL.

    For me, there's no doubt that delta.com calculates different MQMs on the trip summery page (at booking) from the listed miles on the flights you can see when checking flight status.
    What I'm not so sure about is if I will get the highest or the lowest possible miles. I'm in the US right now, and on the way over here I actually got the highest number + 15 and had one segment i EU and one transatlantic. And from my skymiles activity log, I could see that I got +5 last time on a ATL-LAX segment.

    So my theory right now is that DL gives the number of miles from the flight # (e.g. flight status) and then adds 10 for international and 5 for domestic/EU segments.

    Perhaps just to shut up us medallion members ;)
