Pets

Pet transport

Varies

An eligible pet may travel in an under-seat carrier or in the climate-controlled baggage compartment when space, aircraft, breed, date and destination rules allow.

More details
  • Fees range from $100 to $200 each way per kennel or carrier; reserve space in advance and review the applicable health, carrier and route requirements.
  • Pets traveling without their passenger use the airline's cargo program.

Special baggage

Sports equipment

Varies

Sports equipment on Alaska's approved list travels as checked baggage when packed in a case intended for that equipment.

More details
  • It normally uses the applicable checked-bag rate, and Alaska waives oversize or overweight charges for many listed items; contents outside the equipment and item-specific size, weight, route or aircraft limits can still trigger charges or refusal.

Musical instruments

Varies

An instrument may use the cabin allowance only when it fits safely in available stowage.

More details
  • Larger instruments can travel on a purchased cabin seat under Alaska's conditions or be checked in protective packaging; acceptance depends on the instrument, aircraft, dimensions and weight.

Allowed

Alaska accepts wheelchairs and mobility aids in addition to normal baggage, subject to device, stowage and battery-safety rules.

More details
