Minerva Galvan Domenech from Spain told news website Spiegel Online that passengers, some of them bleeding from their ears, mouth or nose, had to wait 45 minutes before being allowed to leave the plane.
German police said 33 of the 189 passengers on board were taken to a nearby hospital after complaining of headaches, ear pain and nausea. All were able to leave again by Saturday morning.
Passenger Conor Brennan told the Irish Times newspaper that “airport staff and Red Cross did their best to handle the situation, as Ryanair were nowhere to be seen.”
“They really displayed a shocking lack of empathy for their customers, almost bordering on inhumane,” he was quoted as saying.
Galvan Domenech said many passengers had to spend the night at the airport, some of them lying on the ground, according to Spiegel Online.
Ryanair said passengers received refreshment vouchers but there was “a shortage of available accommodation.” Frankfurt-Hahn has long been a major base for Ryanair.
A replacement flight took some of the passengers to Croatia on Saturday.
Ryanair has long been dogged by accusations of poor service and bad treatment of staff. Last week, Ryanair pilots in Ireland staged their first strike and two more walkouts are planned July 20 and July 24.
