Complaint Letter: Extended Maintenance Delay

Problem/Feature Description

Rachel Kim has been a loyal Delta Air Lines customer for 11 years, has accumulated approximately 900,000 lifetime miles, and holds Platinum Medallion status. On January 14, 2026, she was booked on Delta flight DL408 from Los Angeles (LAX) to New York (JFK) in business class — a ticket she purchased for $1,847.

The flight sat on the ground for 7 hours due to a maintenance issue. No explanation or estimated timeline was communicated to waiting passengers. Gate agents repeatedly said the flight was "almost ready." No meal vouchers or refreshments were offered during the delay. When Rachel directly asked a gate agent about compensation, she was told to "call customer service."

As a result, Rachel missed her client board presentation that had been scheduled months in advance — an event she had traveled specifically to attend. The client had to reschedule the meeting with other vendors present, resulting in tangible professional damage. Rachel wants to write a formal complaint letter to Delta, as she feels the airline's handling of the delay falls far short of what she was promised as an elite member.

Output Specification

Write the complaint letter as letter.md. The letter should be addressed to Delta Air Lines and should draw on any relevant Delta policies, commitments, or regulatory frameworks you can research. Rachel's desired outcome is: reimbursement of out-of-pocket expenses incurred during the delay plus a meaningful miles credit appropriate to her loyalty status and the severity of the disruption. She also wants a written response from Delta.
