🟢sos_check_rights(type, origin, destination, carrier, arrival_delay_minutes, ...)
Checks a cancelled, delayed, overbooked or missed-connection flight against EU261, UK261 and US DOT rules. Returns the law that applies, up to three options (refund, re-routing), the care the airline owes (meals, hotel), a compensation range per passenger with its conditions, warnings and facts that would sharpen the answer. Advice only, not legal advice.
