Re: Formal Demand for Compensation
Confirmation Code: [XXXXXX]
Flight Number(s): [DL XXXX]
Date(s) of Travel: [date]
Route: [origin] → [destination]
Issue: [Involuntary Denied Boarding / Flight Cancellation /
Significant Delay / Lost Baggage / Refund]
Amount Demanded: $[amount]
To Whom It May Concern:
I am formally demanding compensation for the incident described below.
**INCIDENT DESCRIPTION:**
[Choose applicable:]
INVOLUNTARY DENIED BOARDING:
On [date], I was involuntarily denied boarding on Delta flight [DL XXXX]
from [origin] to [destination], scheduled to depart at [time]. I held
a confirmed reservation (confirmation code [XXXXX]) and arrived at
the gate by [time].
Delta representatives informed me at [time] that the flight was
oversold and I would not be accommodated. I was [offered / not offered]
alternative transportation, ultimately arriving at my destination at
[actual arrival time] — [X hours/days] after my scheduled arrival.
Under 14 CFR Part 250 (DOT denied boarding regulations), Delta owes
me 400% of my one-way fare, not to exceed $1,550. My one-way fare was
$[amount], entitling me to $[amount].
Delta [paid / offered only $[amount] / paid nothing]. I am demanding
the full regulatory compensation of $[amount].
FLIGHT CANCELLATION — REFUND:
Delta cancelled flight [DL XXXX] on [date]. I elected not to travel
on the alternative rebooking offered. Under DOT regulations and Delta's
own refund policy, I am entitled to a full cash refund to my original
payment method for the full value of the ticket(s).
Delta has [not issued the refund / issued a travel credit instead of
cash / only partially refunded]. I am demanding a full cash refund of
$[amount] to my [credit card ending in XXXX / original payment method].
Note: DOT rules explicitly require cash refunds to the original payment
method — travel credit is not an acceptable substitute.
SIGNIFICANT DELAY — EXPENSES:
My flight [DL XXXX] on [date] was delayed [X hours] due to [reason
Delta gave]. As a direct result of this delay, I incurred the following
extraordinary expenses:
- Hotel: $[amount] (receipt enclosed)
- Meals: $[amount] (receipt enclosed)
- Alternative transportation: $[amount] (receipt enclosed)
- [Other: e.g., missed connecting flight costs] $[amount]
Total expenses: $[amount]
Delta's meal voucher offering of $[amount] was [refused / insufficient].
Delta's responsibility for these expenses arises from its delay, which
was within its operational control.
LOST / DAMAGED BAGGAGE:
Delta lost/damaged my baggage on flight [DL XXXX] on [date]. I filed
a Property Irregularity Report (PIR # [XXXXXX]) at baggage claim on
[date].
My bag contained: [describe items and values]
Total value: $[amount]
Delta's settlement offer: $[amount] / [no offer made]
Under DOT regulations, Delta's maximum liability for domestic flights
is $3,800. My claim of $[amount] is within this limit. I have provided
documentation of the contents' value (receipts enclosed).

FAQs
Q: Delta says my delay was due to "weather" — do I have any rights? A: Weather delays are generally exempted from EU261 compensation (extraordinary circumstances). For U.S. DOT, weather delays are also generally exempted from involuntary denied boarding compensation. However, if weather only caused part of the delay and Delta's operational issues caused the rest, you may have partial claims.
Q: Delta gave me a travel credit instead of a refund. Is that acceptable? A: No — for cancelled flights or significant delays where you choose not to travel, DOT rules require a cash refund to the original payment method. A travel credit is not compliant. Demand cash refund and file DOT complaint.
Q: My baggage was delayed (not permanently lost). Do I have compensation rights? A: Yes — for delayed baggage, you can claim reasonable expenses incurred while waiting for your bag (clothing, toiletries). Keep receipts. Delta's liability for delayed bags is capped at the same $3,800 domestic limit.
