Also, about upgrades:
Currently you can only use your Continental mileage plus miles to upgrade on CO
is very stingy about upgrading with miles which is why they are not one of the "mileage-upgradable" carriers. Not sure how their elite system works if that's what you're wanting to know about. Assuming all the trips listed above are round-trips you'll be about 3 thousand miles short of CO
elite. But I'm sure you'll find some way to get them.
