I am writing this letter to apply for the position of Airline ground staff at ABC . I have been well familiar with your company products for many years and would be very excited to have an opportunity to work for your company and help increase the sales of your products. The position was introduced by a friend of mine, Dr. Peter Ho, whom I have contacted directly for this position. I have worked with him for many years in the industry and I believe that I am a perfect candidate for this position.
