The Business Minister Heather Humphreys has said people whose flights are cancelled are entitled to a full refund.
She was speaking amid concerns that some airlines have offered customers vouchers as compensation for cancelled flights, instead of cash refunds.
Under EU law, customers are entitled to a refund for flights that do not operate.
If a flight is cancelled, regardless of when you are told about the cancellation, your airline must offer you the choice between re-routing as close as possible to the original departure time, re-routing at a later date or a refund of the cost of the unused flight ticket.
The European Consumer Centre Ireland says where a flight is cancelled an airline is "obliged to respect the passenger rights" that remain unchanged, even under circumstances such as COVID-19.
Minister Humphreys has told Pat Kenny she is in contact with the Competition and Consumer Protection Commission (CCPC) over the issue.
"We're certainly looking at that matter.
"I know that some travel agents have found themselves in a very difficult situation."
"The CCPC will certainty look at all of those issues and I am in conversation with them."
She said: "It's important that people do get refunded for the cost for flights that were cancelled."
"They're entitled to their money back obviously under law, so therefore they should get their money back under law.
"But there are some issues that need to be teased out yet, and I'm working with the Consumer Protection Commission on that matter.
"A refund is absolutely - there's no doubt about that - but whether it's a cash refund or whether it's through vouchers, as I said, I'm looking at that at the minute".
