"There is no compensation scheme here"
medium likelihoodThe carrier says the country has no passenger-rights regime, or that its conditions of carriage are the only thing that applies.
What answers it
That is not right: Ley de Aviación Civil (Ecuador) and Ley Orgánica de Defensa del Consumidor govern this. Ask the carrier to state, in writing, which provision it says applies to your flight and what it provides. A carrier that will not answer that question in writing is one you take to the regulator.

"Only the Montreal Convention applies"
medium likelihoodOn an international flight the carrier says the Montreal Convention is the exclusive source of its liability, so no national consumer remedy is available.
What answers it
The Convention governs claims for damage — death, injury, baggage, and damage occasioned by delay — and it is exclusive for those. It does not displace a national regulator’s power to require assistance, rerouting or a refund, which are regulatory obligations rather than claims in damages. Plead them separately.
