What service is offered to passengers who require medical assistance during the flight?

The correct choice highlights an essential aspect of airline service regarding medical needs. When passengers require medical assistance during a flight, airlines typically have protocols in place to handle such requests. This means that if a passenger informs the airline about their medical condition or need for assistance, the airline can arrange for the necessary support, whether that involves having trained personnel on board, preparing equipment, or coordinating care with ground services upon landing.

This flexibility ensures that the specific needs of each passenger are met on a case-by-case basis, rather than assuming a one-size-fits-all approach. The option captures the essence of how airlines like Ryanair prioritize passenger safety and comfort by responding directly to individual requests for medical assistance.

The other choices imply a certain standard procedure that may not universally apply to all flights or situations. For example, having a doctor travel with the passenger or a paramedic always accompanying flights may not be feasible or necessary in every case. Likewise, supplemental oxygen availability may depend on specific passenger needs rather than being provided automatically. Therefore, the correct choice reflects the airline's ability to cater to unique medical requests as they arise.
