Passengers on a Monarch Airlines flight reportedly faced an 18-hour delay after their aircraft was diverted following three separate medical emergencies.
The flight to Birmingham from Gran Canaria landed at Porto on Portugal on the night of September 12.
But after landing the aircraft was grounded as crews were unable to replace oxygen supplies that had been used in the emergencies.
Crews were sent to hotels – but families were kept in the airport with no food, the Birmingham Mail reported.
The airline offered affected passengers £100 in flight vouchers and apologised, but has refused compensation.
In a letter sent to a passenger Monarch said: “It is extremely unusual to encounter the number of unforeseen and unpredictable medical issues requiring oxygen support during this flight rotation.
“We understand it will offer little consolation after spending an extremely uncomfortable night in the airport terminal but please be assured that, had we been able to accommodate you, we would have done so without hesitation.
“We are aware that the arrangements were less than satisfactory and can only reiterate our apology.
“We were very disappointed that we were not able to secure the required oxygen supplies in the first instance and the situation was only further complicated by the closure of terminal facilities over the period of your enforced stay.
“We remain grateful that we were able to source stocks of thermal blankets from the local fire service in an attempt to provide some comfort during this unfortunate turn of events.
“In this instance, whilst the events which occurred during the delay were below the standard we would have wanted to provide, the cause of the diversion, a medical emergency, was clearly beyond our control and could not have been avoided.
“Despite all that occurred being completely beyond our control, we would like to provide you with a £100 voucher which is redeemable towards a future Monarch flight.”
