The six things a written baggage claim has to contain, the mistakes that make airlines stall, and a worked letter with the current limits filled in.
The phone call and the airport report are not the claim. The written claim is. It needs to reach the airline within the deadline for your trip, and it needs to contain enough that the airline cannot bounce it back for “more information”.
The two things that change how the airline responds: citing the rule that applies with the correct current limit, and arguing your list up to the cap rather than accepting the airline’s depreciation table. A claim that shows its arithmetic gets handled by someone who can approve it.

Short, dated, itemized, and citing the rule. Here is the shape of one for a lost bag on an international trip, with the numbers a claim of that kind typically carries: the reference line with flight, date and file reference; one paragraph of facts; one paragraph naming the Montreal Convention, Article 17(2) for the loss, Article 22(2) for the 1,519 SDR limit at 1.37 US dollars per SDR; the contents at replacement cost, $2,745 across six lines, with the schedule attached; the interim purchases, $251, receipts attached; the total claimed under the liability provisions, $2,081, because the documented loss exceeds the limit; the bag fee, $75, refunded on top under the DOT refund rule; and a demand for payment within 30 days, by bank transfer, not vouchers.
Whatever the airline’s baggage page accepts, and most US airlines now accept only their own web form. The form usually has a comments box: paste the letter there in full and copy the amounts into the form’s own fields. Where the airline publishes a claims email, send the letter as the body with the schedule and receipts attached. Where only a postal address exists, use tracked mail and keep the receipt as proof of the claim date. Your airline’s page on this site lists what a person has verified for it.
On the day after the deadline you set: one paragraph restating the claim, the date it was sent, the date the answer was due, and a new date seven days out, with a sentence that a complaint to the Department of Transportation follows if that date passes. That letter changes who reads the file.
Yes. Enter a trip in the claim builder and the letter for it appears as you type, addressed to your airline with the current limits and your deadlines filled in, before anything is signed.
Whatever the airline’s baggage page says it accepts. Most take a web form or email; a few still require post. Your airline’s page on this site lists what we have verified.
