Flying With CPAP on Qantas and Jetstar
⚡ Key Clinical Takeaways
- In Australia, a CPAP machine is classified as a medical device rather than standard luggage.
- Qantas permits one standard carry-on bag up to 7 kg plus the CPAP machine in its own bag.
- Inflight power outlets are not guaranteed on domestic Qantas Boeing 737 or Airbus A320 fleets, and Jetstar's A320/A321 fleet generally lacks seat power in economy.
- Carry a letter from your GP or sleep physician dated within the last 12 months.
- At the screening point, remove the CPAP from its bag and place it in a separate tray, similar to a laptop.
Quick answer: Flying With CPAP on Qantas and Jetstar is straightforward when you prepare correctly. Both airlines allow CPAP machines as additional carry-on items that do not count toward your standard baggage allowance. You must carry a doctor's letter, ensure batteries meet IATA watt-hour limits (typically under 160 Wh), and notify the airline at least 48 hours before departure if you plan to use the device inflight. Mains power is not guaranteed on domestic flights, so battery operation is essential.
How Australian Airlines Classify CPAP Devices
In Australia, a CPAP machine is classified as a medical device rather than standard luggage. Qantas and Jetstar both follow Civil Aviation Safety Authority (CASA) guidance and International Air Transport Association (IATA) dangerous goods regulations. This classification means the device travels free of charge on top of your normal carry-on allowance. You should still pack the machine in a protective case and keep masks, tubing and humidifier chambers accessible for security screening. The classification applies equally to fixed-pressure CPAP, APAP and bilevel devices such as VPAP or BiPAP.
Carry-On Rules and Cabin Baggage Allowances
Qantas permits one standard carry-on bag up to 7 kg plus the CPAP machine in its own bag. Jetstar allows one main item up to 7 kg (or 10 kg with FlexiBiz) and the CPAP as an extra item. Neither airline weighs the medical device separately, but the bag must fit under the seat or in the overhead locker. If you also carry a laptop bag or handbag, that counts as your personal item. Pack the CPAP last so it can be removed quickly at security. A typical ResMed AirSense 11 or Philips DreamStation 2 weighs around 1.2 kg to 1.5 kg without the humidifier.
Battery Requirements and Watt-Hour Limits
Inflight power outlets are not guaranteed on domestic Qantas Boeing 737 or Airbus A320 fleets, and Jetstar's A320/A321 fleet generally lacks seat power in economy. You must bring a battery if you intend to use CPAP during the flight. IATA rules allow lithium-ion batteries up to 100 Wh without airline approval, 100–160 Wh with airline approval, and prohibit batteries over 160 Wh. A common CPAP-specific battery such as the Medistrom Pilot-24 Lite (95 Wh) or Pilot-12 (99 Wh) falls under the 100 Wh threshold. Carry a maximum of two spare batteries in carry-on only; terminals must be protected against short circuit.
Comparison of Qantas and Jetstar CPAP Policies
| Feature | Qantas | Jetstar |
|---|---|---|
| Carry-on weight limit (main bag) | 7 kg | 7 kg (10 kg FlexiBiz) |
| CPAP as extra item | Yes, free | Yes, free |
| Inflight power availability (domestic) | Limited, mainly Business | Generally none in Economy |
| Medical clearance form required | Only if using inflight | Only if using inflight |
| Advance notice for inflight use | 48 hours | 48 hours |
| Battery approval 100–160 Wh | Email special handling | Online form or call centre |
Medical Documentation You Need
Carry a letter from your GP or sleep physician dated within the last 12 months. The letter should state your diagnosis (usually obstructive sleep apnoea), confirm the device is medically necessary, list the pressure settings in cm H2O, and authorise battery carriage. Qantas and Jetstar do not routinely ask to see this letter at check-in, but security staff or cabin crew may request it if you use the device inflight. Keep a printed copy with the machine and a digital copy on your phone. If you hold a commercial driver's licence under Austroads guidelines, the letter can also support your fitness-to-drive documentation.
Security Screening at Australian Airports
At the screening point, remove the CPAP from its bag and place it in a separate tray, similar to a laptop. Masks and tubing can stay in the bag unless asked. Officers may swab the device for explosive trace detection; this is routine and takes seconds. Do not check the CPAP in hold luggage — pressure changes and baggage handling can damage the blower motor and humidifier seal. If you travel with distilled water for the humidifier, containers over 100 ml must go in checked baggage; consider using waterless humidification (HME filters) or buying distilled water at your destination.
Using CPAP During the Flight
If you plan to use CPAP inflight, you must notify the airline at least 48 hours before departure. Qantas requires an email to special.handling@qantas.com.au with flight details and battery watt-hour rating. Jetstar uses an online "Medical Equipment" form or the call centre. Cabin crew will verify your battery is secured and may ask to see the medical letter. Use a window seat to keep tubing clear of the aisle. Turn off the heated humidifier to conserve battery; most machines run 6–8 hours on a 95 Wh battery at 10 cm H2O without humidity. Set the device to airplane mode if it has wireless connectivity.
Step-by-Step Pre-Flight Checklist
- Confirm flight details and notify the airline (48+ hours before).
- Obtain a current GP or specialist letter with pressure settings.
- Charge all batteries fully; verify each is under 160 Wh and terminals are taped.
- Pack CPAP, mask, tubing, power supply and batteries in a dedicated carry-on bag.
- Print two copies of the medical letter; save a photo on your phone.
- Arrive at the airport 30 minutes earlier than usual to allow extra screening time.
International Connections and Transit Considerations
On Qantas international flights (e.g., A380, 787), seat power is widely available in all classes, but you still need airline approval for batteries over 100 Wh. Transit through Sydney, Melbourne or Brisbane domestic terminals requires re-screening; keep the CPAP accessible. Some Pacific Island carriers and Asian airlines apply different watt-hour limits or require a specific medical information form (MEDIF). Check the operating carrier's policy, not just the marketing carrier, when booked on a codeshare. Carry a universal plug adapter for overseas hotel use, as Australian Type I outlets are not standard abroad.
Troubleshooting Common Issues
If the battery fails mid-flight, switch to passive breathing — the mask vent allows air exchange without pressure. Pack a spare mask cushion and tubing connector in case of leaks. If the device alarms for high leak, check the mask fit and ensure the humidifier chamber is seated correctly. For pressure discomfort at cruise altitude, some clinicians suggest reducing pressure by 1–2 cm H2O temporarily; discuss this with your sleep physician before travel. On arrival, run the machine for 30 minutes before sleep to clear any condensation. If equipment is damaged, Australian consumer law covers repairs under the manufacturer's warranty; contact the local distributor (ResMed Australia or Philips Respironics Australia) rather than the airline.
Frequently Asked Questions
Does CPAP count as carry-on luggage on Qantas or Jetstar?
No. Both airlines allow a CPAP machine as an additional item free of charge on top of your standard carry-on allowance.
Can I use my CPAP on a domestic flight without a battery?
No. Mains power is not guaranteed on domestic Qantas or Jetstar aircraft; you must bring a compliant battery if you intend to use the device inflight.
What battery size can I take without special approval?
Lithium-ion batteries up to 100 Wh can be carried without airline approval. Batteries between 100 Wh and 160 Wh require airline approval; over 160 Wh are prohibited.
Do I need a medical letter for domestic flights?
Yes. Carry a letter from your GP or sleep physician dated within 12 months stating the medical need, pressure settings and battery authorisation.
Can I pack distilled water for the humidifier in carry-on?
Only containers of 100 ml or less are permitted through security. Consider waterless HME filters or purchasing distilled water at your destination.
What happens if my CPAP is damaged during the flight?
Report damage immediately to the airline baggage service desk and obtain a property irregularity report. Manufacturer warranties through ResMed Australia or Philips Respironics Australia cover defects; travel insurance may cover accidental damage.
