Spend on hotel stays was up 30% in April compared to March, according to new debit and credit card data from AIB.
The boost in spend follows clarity from the Government on the reopening of the sector, which is set for June.
Those under the age of 25 recorded the highest increase in hotel spending, with a rise of 38%.
The data shows the lowest increase was among those between the ages of 45-54.
In terms of airline spending for the month of April, those over the age of 65 recorded the biggest increase, up 25% on the previous month.
Those between the ages of 25-34 recorded the smallest increase in airline spending, up just over 2%.
Rachel Naughton, Head of SME Banking at AIB said that during April, consumer spending was also up in other hospitality sectors.
"These include pubs and off-licences - up 35%, and restaurants - up 9% as consumers took advantage of the good weather.
"We hope to see this positive trajectory continue over the coming months," she said.
