Oxygen needs

Although WestJet does not provide oxygen 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.

Gaseous oxygen acceptance

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

  • when the necessary documentation has been provided;
  • on domestic flights. We are unable to accept oxygen from guests on flights outside of Canada;
  • in the cabin as a carry-on medical device;
  • if the cylinder is free of cracks, defects or other visible damage and free of flammable contaminants;
  • if the cylinder has a permanent 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, bring extra batteries with you to ensure that your oxygen's regulator can continue to operate.
  • 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 prior to 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 prior to your flight's departure date;
  • indicate the model number of each medical oxygen cylinder;
  • verify that each medical oxygen cylinder conforms with the manufacturing, packaging, marking and labelling requirements of the Transportation of Dangerous Goods Regulations;
  • verify that each medical oxygen cylinder has been maintained by a Canadian supplier in accordance with applicable standards;
  • verify that each medical oxygen cylinder has been hydrostatic tested by a Canadian supplier in accordance with applicable standards;
  • verify that each medical oxygen cylinder gauge does not exceed the rated cylinder pressure.

Portable oxygen concentrators (POC)


Guests requiring oxygen on board the aircraft are permitted to travel with an approved portable oxygen concentrator (POC). This service is offered on all flights and there is no limit to the quantity of POCs allowed on board. Other POCs not included on this list may be carried on board, but may not be used.


The following 21 approved POC models may be used on board all WestJet flights (other POCs may be allowed on board, but not used). Approved POC models are manufacturer tested in accordance with Section 21, Category M, of RTCA/DO-160F and must be affixed with a label of compliance.

  1. AirSep FreeStyle
  2. AirSep FreeStyle 5

Battery acceptance

Your POC may only be used in the battery-operated mode and you must have enough fully charged batteries for the duration of your flight as well as any unanticipated delays. Extra batteries must be packaged for carry-on in a manner that will prevent a short circuit. Battery terminals must be either recessed or packaged so as to prevent contact with metal objects, including the terminals of other batteries. Batteries are only accepted as carry-on.


When travelling with a POC, you must present a physician's statement to the Customer Service Agent at check-in, as well as to the flight attendant upon boarding. The letter must be on your physician's letterhead with an issue date of no more than one year prior to your flight's departure date. 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.
