Oxygen needs

Although WestJet does not provide medical oxygen for purchase on board, we may accept certain gaseous oxygen and portable oxygen concentrators on 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.

WestJet permits a maximum of two guests travelling with gaseous oxygen cylinders per flight, and a maximum of two cylinders per guest, and only:

  • when the necessary documentation has been provided;
  • only on WestJet-operated domestic flights. We are unable to accept guests' oxygen on flights to or from any other destination;
  • 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.
  • Therefore, gaseous oxygen cylinders are not permitted in the bulkhead rows;
  • if the cylinder is free of cracks, defects or other visible damage and free of flammable contaminants;
  • if the cylinder has a regulator attached (because 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 does not exceed a maximum weight of 5 kg (11lb);
  • if the cylinder is an accepted model and does not exceed the following dimensions:



M-6 30.5 cm long x 9 cm wide
(12 inches long x 3.5 inches wide)
41.9 cm long x 11.5 cm wide
(16.5 inches long x 4.5 inches wide)

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. We recommend sitting in specific seating, to ensure adequate spacing for the oxygen cylinder.

Your POC may only be used in the battery-operated mode and 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. If you need to use your POC at all times (including taxi, inflight and landing), your device needs to be tested and approved for air travel. Your POC must be labelled with a RTCA/DO 160 sticker or this information must be included in your user's manual.

When travelling with a POC intended for use on board the aircraft, you must present a physician's statement to the WestJet Agent at guest assistance, as well as to the flight attendant upon boarding.

The letter must be on either your physician's letterhead, WestJet's physician's statement or one of our airline partners' oxygen/POC forms. Whichever form you use, it must have an issue date of no more than one year before the departure date on the last flight on your itinerary. The letter must state that:

  • the oxygen is medically required for all portions of the flight (taxi, take-off, cruise and landing);
  • the user has the ability to see, hear and understand the device's cautions and warnings and that they are able to respond accordingly without assistance. If not, the user must travel with a companion who is capable of performing these functions on their behalf;
  • the maximum flow rate corresponds to the pressure in the cabin under normal operating conditions. Cabins are pressurized to an altitude of approximately 8,000 feet.
