People travelling from Dublin Airport during Level Five have been able to avail of pubs, restaurants and some shops.
The airport is deemed an essential service with a limited number of businesses allowed to operate after security inside the terminals.
People can still avail of a pre flight pint although they are under the €9 substantial meal rules that were part of regulations earlier this summer.
A Dublin Airport spokesman said: "The Government has indicated that the operation of Irish airports is an “essential service” within the Level 5 guidelines.
"The provision of food and beverage facilities in the airside area – i.e. after security - to the very small number of people who are travelling at present is part of that service. The operator of the outlet in question requires anyone purchasing alcohol to also purchase a substantial meal at a cost of €9."

Just over 6.9 million passengers have travelled through Dublin Airport between January and October this year, which is a 76% decline on the first 10 months of last year.
