Travel Advisory
Mexico Travel

Alaska Airlines and Horizon Air continue to monitor the current conditions surrounding the outbreak of influenza in and around Mexico. The safety of our customers and employees is our highest priority. The following options are being provided if your travel is impacted by the outbreak.

If you're traveling to/from Mexico from April 27 through May 20, 2009, you're allowed to make the following changes:

* Change fees and/or additonal fare collection will be waived if the rescheduled flights are booked in the original class of service to the same city pairs as originally ticketed. Rescheduled travel must commence on or before May 20, 2009.
* If new travel commences after May 20, change fees will be waived, however, additional fare collection will apply if the fare has increased.
* If you wish to keep your travel date, but change your destination, you won't be charged a change fee, however you will be charged or credited a difference between the new and old fares.
