Good news, CPAP users. I complained to CX and asked them to revise their CPAP policies. I was shocked to receive a call from the airline agreeing with me. Lo and behold, the policies have, in fact, been changed!

First, you no longer need to call 48 hours in advance to clear CPAP use if you have a FREMEC card.

"If you are a regular traveller onboard Cathay Pacific or Cathay Dragon, you can apply for a Frequent Travellers Medical Card (FREMEC). If you hold a FREMEC card, you no longer have to submit the details of your device each time you fly with us, provided there has been no change in your condition or the assistance required."

Second, they now clearly state CPAP users do not require medical clearance.

" Passengers who only require the use of a CPAP or BIPAP machine inflight do not need medical clearance."

Third, and this is really good, you can use in-seat power for your device:

"For non-critical medical portable electronic devices (e.g. CPAP or BIPAP machines, nebulisers, neurostimulators, HR/BP monitors, syringe/feeding pumps, suction devices and aspirators, external or transcutaneous nerve stimulators e.g. TENS machine), please note the following:
All non-critical medical portable electronic devices can either be connected to the inflight laptop power 110VAC outlets (where available) or be self-powered using approved dry-cell or gel-type battery packs in accordance with all applicable regulations."

On this last point, your device may draw more power than the laptop outlet can manage, but it's worth a try. I used to make use of the seat power back in the days before it was outlawed.

Happy days.
