Stripped to its essentials, your GP logged you as asthmatic 18 months ago. The AvMed Docs may then require you to return in 2 1/2 years time.
Your word against his. As you say, only by getting down to the AFCO will you find out.
Hopefully they'll be sensible and look at my situation properly. I imagine the GP noted my comments about not having asthma and additionally see that I have only ever been tested once which was many years ago. I've never been hospitalised or seen a GP due to an asthma attack. I'm just hoping that they give me a chance to argue my case... my lawyer training will then come in handy!
