Probably a daft question!

Seriously considering a career change as the airline industry is almost on its knees but I’m worried that I will be unable to find work due lack of LGV experience.

If experience is a problem, then may I suggest agency work?, I had none at all and was soon tooling round the country with various different companies / units / trailers. This, for me has been an invaluable way to get at least a little bit of experience, hopefully to propel me to bigger and better things.

Good luck with whatever decision you make
