Unfortunately we can’t accept a request for 4 litres continuously/intermittently on flights between Dublin and San Francisco, Athens, Bucharest, Bourgas, San Francisco or any of the Canary Islands due to the duration of the flight and the aircraft type.

Battery Requirements

Aer Lingus does not provide any onboard power sources for assistive devices. The customer is responsible for providing batteries with enough life to support the trip they are on.

Guided by FAA battery requirements an assistive device user must have 150% of their actual flight time in battery time, regardless of how long the user may choose to use the device or if it is solely intended as a carry-on item.

The appropriate number of batteries should be calculated using the manufacturer’s estimate of the hours of battery life while the device is in use. The expected maximum flight duration is defined as the carrier’s best estimate of the total duration of the flight from departure gate to arrival gate. Aer Lingus will not accept any device that requires a wet cell battery due to safety regulations.

* Due to safety requirements some devices may not be utilized on Aer Lingus Regional Flights. Please contact our special assistance department no less than forty-eight (48) hours prior to travel for verification.

If you have an FAA approved assistive device you may use it in flight by completing the steps below:

  • Complete your travel plans and purchase your ticket.
  • Verify that your FAA approved device will have the FAA required 150% of battery time for your cumulative flight times. (Note that if you carry the device on board but do not intend to use it while in flight you are still required to follow the FAA battery requirements and contact our special assistance department with device information.)
  • Have your attending physician sign and date the medical information form within ten (10) days of your outbound travel.
