About this tool
Hello. This tool calculates how many SkyMiles are earned flying on Delta and its partners. Plan your trips — or mileage runs — to maximize mileage earning, or just see where you'll end up this year with your miles obsession.
Type your route. jfk-atl-sfo-atl-jfk is a round trip
from New York JFK to San Francisco with a stop in Atlanta, all on Delta,
using the "Default fare" specified above. Enter more trips on separate
lines.
Specify carrier and fare bucket by typing something like
ke.f between the airport codes; that means that the segment
is on Korean Air in the F fare bucket. Omit the carrier code to default
to DL, such that y means Y on Delta. So,
jfk-k-atl-ke.c-icn means New York JFK to Atlanta on a K
fare on Delta, then onward to Seoul Incheon on Korean Air on a C fare.
To see your cost per mile for a trip, type the fare too. For
example: lga-mdw-lga $199.
Revenue-based redeemable miles will be estimated for all-Delta
trips. If you specify more than one dollar amount on the line, only the
first will be used for this calculation, since Delta does not give you
miles for government taxes and fees. The sum will be used for the other
costs per mile.
This tool does not currently take into account Delta exception fares such as consolidator and cruise fares which can still earn redeemable miles based on distance flown.
If you received bonus miles include that amount as well. For
example: jfk-lax-jfk 500 would specify a trip from New York
to Los Angeles that you got a 500-mile redeemable miles bonus for.
Delta's guide to miles earning on its own tickets is here and with partners is here. I make my best guess, but remember that this website is not affiliated in any way with Delta Air Lines. No guarantee of accuracy is made; Delta is the final authority on how many miles they actually award. A discrepancy of a few miles can be expected because I probably round numbers a bit differently than Delta does. If you get a really incorrect result, I'd appreciate hearing about it so I can fix it (I'm @michaelpanik on Twitter; or email me).
