Airline by airline
How each airline handles a claim
The law is the same whoever you flew. What differs is where the claim has to go, how long they take, and which defence they reach for first.

If the airline is stonewalling
The airline pages above tell you what response patterns to expect. When a carrier ignores letters or recycles a refusal, a no-win-no-fee claims service with a legal team is often what finally moves it — airlines settle faster when court papers are a real prospect.
Compensair takes 25–35%, AirHelp 35–50% when legal action is needed — AirHelp is the stronger pick against a stonewalling airline. Affiliate links; your fee is unchanged either way.
