ExpertFlyer.com is offering a 10% discount (usually $99.99) on a premium membership gift certificate through December 24 by using coupon code HOLIDAY2010. ExpertFlyer is one of the most useful travel tools out there. It’s useful for checking fare buckets, seatmaps, fare rules, and award space for a few airlines that are otherwise tough to search, along with offering the ability to set seat and availability alerts. It’s probably not worth it for the occasional flyer, but can be very useful. It’s especially useful for checking award space on airlines that are otherwise not all that easy to search online, like Air France, Air Tahiti Nui, Emirates, and a few more.
As someone that spends hours a day planning travel for people, it’s invaluable.
