Kids Fly Free: Basically, with this deal at Alaska Airlines, one child can fly free with each accompanying adult-- note that a "child" is age 2 to 11-- on flights to a number of Southern California airports. Families must book a "complete vacation package" including hotel, too.
This deal combines with other promotions offered at Disneyland, such as a "Save up to 35% at a Disneyland Resort Hotel", and free nights and other deals at a number of hotels in the area.
Read all the details and fine print at Alaska Airlines' Kids Fly Free to Disneyland page.
In previous years, the booking date for this promotion was extended -- there's no guarantee, though, that this will repeat in 2011.
Families can also check Special Offers at the Disneyland Resort site, for promotions such as hotel discounts and packages.
