Alaska Airlines is taking a page from the Domino’s Pizza playbook and offering a delivery guarantee. But it’s not for pizza, it’s for checked bags:

Effective July 7th, if your baggage is not at the baggage claim within 25 minutes of your plane parking at the gate, you’re entitled to a certificate for either a discount code for $25 off a future Alaska or Horizon flight or 2,500 Alaska Airlines Mileage Plan bonus miles. If we don’t meet our 25 minute guarantee, simply see an Alaska or Horizon Customer Service Agent and let them know. They’ll ensure that you receive your Baggage Service Guarantee certificate or Bonus Miles.

Vouchers? That’s a “guarantee,” but not a money-back guarantee. Especially since Alaska just launched a fee per bag. If they charge cash, then a guarantee should offer cash refunds. Seems pretty straightforward.

There’s another catch: The guarantee is only valid from July 7 through December 15, 2009. Expect an extra effort from the baggage handlers during this window.

But wait, there’s more! And as an added bonus, the guarantee can be nixed if conditions aren’t perfect:

Alaska and Horizon reserve the right to suspend the BSG in cases of airport baggage system malfunctions, severe weather events, or other conditions out of the airlines’ control that limit or prohibit timely baggage delivery.

Call me a cynic, but I’d expect the invocation of that clause on a regular basis. But points for marketing creativity. Maybe soon we’ll learn have an airline teach us to Avoid the Noid.
