Why a short, simple complaint works
The longer and more tangled a complaint is, the harder it is for an agent to identify what you want and whether the company owes it to you. The Points Guy ombudsman reviewed cases where travelers included long histories, unrelated incidents and lists of grievances. Those submissions turned straightforward requests into a maze and delayed or prevented correct outcomes.
Another traveler believed they'd paid Costco Travel for two ship cabins but the booking showed one. That kind of mix-up can arise when complaints go to the wrong company or when the submission doesn't clearly identify which provider must act.
How to structure a complaint letter that produces results
Start with a one-sentence summary: the precise problem and the remedy you want.
- Booking reference, ticket number or reservation ID.
- Exact date and flight/hotel/car/cruise segment involved.
- What happened (one sentence). Do not include unrelated past incidents.
- Attach copies of receipts, boarding passes, photos, or screenshots.
Explain the rule or policy that supports your request, if known. For example, note that an involuntary downgrade should trigger a refund of the difference in fare or miles when that applies.
State the remedy you want and how you want it delivered (cash, miles, voucher, replacement booking) and set a reasonable deadline for response.
Close with contact information and a brief line about next steps you'll take if the company doesn't respond (escalation to a regulator, dispute with card issuer, or public complaint). Keep that line factual and unemotional.
Be concise. Keep the body to a few short paragraphs plus a clear facts list and attachments. Use plain headings (Summary, Facts, Request, Attachments) so an agent can skim and act. Send everything in one message rather than a series of scattered emails that fragment the record.
Make sure it goes to the right party
If the company rejects a valid claim, escalate: ask for a supervisor or an executive contact, and retain a clear, concise version of your complaint to forward. If a legal or regulatory standard applies (for example, consumer protections governing refunds), reference it in your request.
Save every email, chat transcript and receipt. A concise, well-documented file that shows chronology and evidence makes escalation and third-party review faster and more likely to succeed.
