Rather than worry about age restrictions, I think you should check on the current recruitment and retention rates for that company. If they have a high turn over rate, I would think you would have good shot at a position. If they have a low turn rate, regardless of your age, you may have a challenge in obtaining a position. I would ask their HR department or whoever is responsible for hiring, as to how many open flight positions for which they have recruited in the last 2-3 years. If they have had a number of flight positions for which they have hired, you would stand a reasonable chance of employment, if they have only hired 1 person in the last 3 years, I would look elsewhere.
