Dear Sir,

I am writing to request the booking of a flight for a specific date and destination with certain requirements.

I would like to book a flight from New York City (JFK) to London (LHR) on June 15, 2023. My preferred departure time is in the morning, around 9:00 am, and my preferred arrival time is in the evening, around 7:00 pm.

Furthermore, I am interested in taking advantage of any special promotions or discounted prices that may be available. If there are any deals or discounts currently available, please let me know so that I can take advantage of them.

I am looking for a one-way ticket for one adult. Please let me know what the total cost would be including all taxes and fees.

Thank you for your attention to this matter. I look forward to hearing from you soon and appreciate your help in making my travel arrangements.

Sincerely, NAME_1
