Because airlines keep changing the rules on how many miles you’ll earn on a flight, you need a constant reference point.
And since you’re always staring at a computer, might as well get a miles calculator in your calendar. So enter 30k.
A free plugin for Chrome, 30k allows you to see the award miles, status miles and segments you earn when booking flights on Expedia, travelocity, Orbitz, Hotwire and other third-party travel sites. You can also see which fares are upgradeable with miles and track your memberships (which you’ll have to enter before you start tracking, obviously).
All good until the airlines change the rules again ... so, who knows?
