Good morning all

The breathing team that is part of the support team I look to have decided I need a nippy for overnight - I have the new version 4 with the version 3 as a backup and have already had a 2nd version 4 as the 1st 1 was giving a fault.

Anyway, my question is with flying in a couple of weeks time and I guess I need to take this with me. So what we do?

Do airlines generally allow a nippy as a 2nd item of cabin baggage or what they do?

Best to all
