Final answer:
In most countries outside of the EU, it is the responsibility of the airport to ensure PRMs have necessary assistance.
Step-by-step explanation:
In most countries outside of the European Union (EU), the responsibility for ensuring persons with reduced mobility (PRMs) have necessary assistance falls on the airport.
The airport is responsible for providing facilities and support services to assist PRMs in their travel, such as accessible restrooms, wheelchair ramps, and staff to help with boarding and deplaning.
For example, airlines like easyJet have specific policies in place to ensure that PRMs receive the necessary assistance needed at the airport, during the flight, and upon arrival to their destination.
