Irish tourists stranded in the Algarve could be stuck there for months to come.
Both Aer Lingus and Ryanair have grounded all flights from the Portuguese coastal region, and there are fears that without Government intervention it could be many more weeks before some of the holidaymakers get home.
Despite still advertising flights from Faro to Dublin from May 31, Aer Lingus has confirmed that all flights from the regional airport are cancelled indefinitely.
The Department of Foreign Affairs has urged Irish citizens to make contact with the Irish Consulate in Lisbon and notify it of their presence.
Two retired Irish couples have spoken of their frustration after they struggled with multiple cancellations and problems rebooking flights and receiving refunds from Aer Lingus.
Dominic Ledwidge O'Reilly (80) and his wife Gabrielle Judge (75), from Firhouse, Dublin, are at the point of despair because three separate flights from Faro since April 29 have been cancelled.
The couple received a refund after the airline was contacted by the Irish Independent, but any hopes they had of flying home soon were dashed.
Speaking from their apartment in Cabanas de Tavira near the Spanish border, Ms Judge said they weare eager to get home.
"We are fed up and feel trapped," she said. "We have been here since February 13, and were due to go back on April 30. We have had three cancellations from Aer Lingus.
"We both have underlying health issues and fortunately we have a very good local pharmacist who has helped us, but we have had to pay for a lot of medications."
Ms Judge said she and her husband were finding it difficult to deal with the uncertainty around when they would be able to fly.
"There is no end in sight which is all the more upsetting," she said. "We contacted the Irish consul in Portugal and haven't heard anything.
"There are flights going to Dublin from Lisbon but for us to get there it would require us to take a bus, a train and then another train. We would be so exposed to Covid we would be in danger. We cannot possibly risk it."
Mr O'Reilly, a retired national press photographer, said they were not alone in their plight.
"There are other Irish pensioners here who are in the same boat and some of them are very frail," he said. "We are all looking out for each other and we are trying to keep on the bright side but it's very hard not to feel worried."
Another couple, who asked not to be named, but are both retired gardaí from Co Kildare, have been stranded since April 30. They have continued to pay for their rental apartment, but say that the added costs are a major concern for many Irish people trapped in the same circumstances.
"We are lucky we are in a nice two-bedroom apartment and we are paying a reasonable amount of money but if we have to stay until July or August we are going to have an issue," they said.
"And that is just us, there are a lot of Irish people here in the same boat.
"I think the Government is going to have to repatriate people. There are a lot of people affected by this and many of them are elderly."
A spokesman for the Department of Foreign Affairs has appealed for anyone experiencing difficulties to make contact, saying: "Any Irish citizen who believes an Embassy may not be aware of their presence should register online."
A spokesperson for Aer Lingus said: "We are reviewing our future operating schedule on an ongoing basis and following guidance from relevant governments in relation to when we will be able to operate particular routes."
