I'm flying from Dublin to London with Ryanair.
I'm just wondering if anyone knows whether or not Ryanair will be serving alcohol on such a short flight?
They do sell alcoholic beverages:
It's a long time I haven't flown with them but I would be surprised if they would not. Their regular flight menu obviously includes alcoholic drinks and I could not find any mention of any restriction for short flights anywhere.
I can't see a reason why they would specifically exclude alcohol either. Unlike full-service airlines, who could welcome an excuse to save a bit of money, Ryanair actually stands to profit from the drinks they serve, since you have to pay for them. So if they have the time for any on-board service, I would expect it to include alcohol.
I regularly fly short haul with ryanair and have never been on a flight where alcohol wasn't sold.
