The crisp sandwich has made an appearance on an Irish airline menu, and is proving to be a hit.

Aer Lingus added the sarnie to its on-board menu, after it recognised a ‘definite demand’ for the product.

The crisp sandwiches are made with Tayto branded snacks, and are available on short haul flights from Belfast City Airport.

The combo has reportedly proven popular on Spanish routes where there are more young families.

Aer Lingus retail manager Sinead O’Neill said: "We’re delighted with the initial reaction to the Tayto crisp sandwich coming on board. It’s fair to say the crisp sandwich has experienced a bit of a revival in recent months following a pop-up shop in Dublin as well as a dedicated crisp sandwich café opening in Belfast, so we recognised there was a definite demand for the product.

“Tayto crisps evoke a taste of home that we all know and love, stemming right back to childhood and there is a certain nostalgia associated with it. For this reason we made the decision to include it on our bia menu and we’re thrilled it has been so warmly received.”

This follows the opening of Simply Crispy in Belfast- a shop which opened in January this year and offers over 35 different flavours of crisp sandwich.
