Kudos to Northwest.

So as an elite on NW flying Continental, we still earn Elite upgrade, full mileage, but 50% EQM on select fares. Right?

Then on Delta, we get full mileage, full EQM but no upgrade.

Hmm....what should I choose.....Do I fly the airline who will continue to award me with full benefits(NW), or do I choose the airline with upgrade benefit but less EQM miles, or the one with full EQM miles and no upgrade.
