I was just wondering if anyone knew if i still had a chance of becoming a pilot in the RAF. Or if i cant join the RAF can i still become a commercial airline pilot?

Plus, if your really clever, could please tell me WHY!   WHY! hayfever stops you from becoming a pilot!

Health and fitness
The Royal Air Force requires all recruits to be medically fit to serve worldwide. New entrants undergo intensive training that is both physically and mentally demanding. Accordingly, they must be fit and free from disease or pre-existing injury to meet this challenge.

If your application is accepted, you will be required to pass an occupational health assessment and a fitness test . Your application will be rejected if you fail to meet the minimum acceptable standards for entry in either test.

Before you are examined by a medical officer, you will be asked to declare certain information about your medical history to identify conditions for which rejection is automatic. Please note that your application will be rejected if:

You suffer from Epilepsy, Diabetes, Colitis, gastric disorders or Crohns Disease (or any other long standing bowel disorder).
You have had your spleen removed.
You have had a detached retina or corneal transplant, or had Incisional Keratectomy (i.e. Radial or Astigmatic Keratectomy). However, refractive error corrective surgery may not necessarily prevent you from joining the Royal Air Force.
You suffer from Rheumatoid Arthritis, or any other bone or joint disorder.
You suffer from hay fever causing severe symptoms or wheezing.
You suffer or have suffered from Asthma in the last 4 years. However, if you have been diagnosed previously as suffering from asthma but have remained symptom-free for a continuous 4-year period, you may be considered for RAF ground service but not aircrew.
You have a chronic eye condition.
You suffer from severe headaches or migraine.

You have to realise that they are in a position to select who they want, not the other way round.
