Oxygen needs

Although WestJet does not provide medical oxygen for purchase on board, we may accept certain gaseous oxygen and portable oxygen concentrators on some of our aircraft. We strongly recommend that you advise us of any oxygen needs a minimum of 48 hours prior to travel as there are restrictions on the equipment types and amounts that can be accepted. If you do not provide adequate notice, you may be denied travel.

WestJet accepts oxygen on most flights operating within Canada. We do not permit gaseous oxygen on flights operated using our Boeing 787 Dreamliner.

A maximum of two guests with a maximum of two cylinders per guest may travelwith gaseous oxygen cylinders as follows:

  • when the necessary documentation has been provided;
  • only on WestJet-operated flights within Canada;
  • in the cabin as a carry-on medical device;
  • if the cylinder can be safely and securely stowed under the seat in front of you;
  • if the cylinder is free of cracks, defects or other visible damage and free of flammable contaminants, such as any oily residues;
  • if the cylinder has a regulator attached and the regulator is protected from damage that could cause inadvertent release of the contents. Regulators cannot be changed during the flight. Oxygen cylinders without a regulator will not be accepted for transport due to safety reasons – WestJet cannot assume responsibility for oxygen cylinders that are not accepted for travel. If you are travelling with a battery-operated regulator for your oxygen cylinder you are required to bring enough batteries to reach your final destination, including any unanticipated delays;
  • if the cylinder fits within the sleeve used to transport it onboard the flight. The cylinder may not exceed the following dimensions:
    Circumference: 11.5 cm/4.5 inches
    Length: 41.9 cm/16.5 inches (excluding the cylinder's content gauge and regulator)

Oxygen cylindars with allowed length and circumference dimensions

In order to travel with gaseous oxygen, you must provide the following two signed and dated statements at check-in and upon boarding:

Statement one – on your physician's letterhead which must:

  • be issued no more than one year before your flight's departure date;
  • acknowledge that you are required to use medical oxygen;
  • indicate the maximum flow rate, maximum quantity of oxygen per hour and the maximum quantity of oxygen required for the flight(s);
  • confirm that you have been trained on the operation and use of your oxygen cylinder (if you are unable to do so, we strongly suggest you travel with a personal attendant who can assist you).

Statement two – on your oxygen supplier's letterhead which must:

  • be issued no more than one year before your flight's departure date;
  • indicate the model number of each medical oxygen cylinder; and verify that each cylinder:
    • conforms with the manufacturing, packaging, marking and labelling requirements of the Transportation of Dangerous Goods Regulations;
    • has been maintained by a Canadian supplier in accordance with applicable standards;
    • has been hydrostatic tested by a Canadian supplier in accordance with applicable standards;
    • gauge does not exceed the rated cylinder pressure.

Some seats are restricted when travelling with oxygen, including bulkhead seating. We recommend specific seating locations, to ensure adequate spacing for the oxygen cylinder.

  • Your oxygen concentrator may only be used in the battery-operated mode
  • You must have enough fully charged batteries to power your POC for the scheduled flight duration as well as any unanticipated delays.
  • Extra batteries are accepted in carry-on baggage only and battery terminals must be either recessed or packaged to prevent contact with metal objects (short circuit), including the terminals of other batteries.
  • Please review the information provided on our medical equipment and medications page for more detail.
  • The space available under our seats varies by seat and by aircraft type. If your POC doesn’t fit under the seat, and you need to use your POC during the flight please ask a member of the flight crew to relocate you.
