We will be flying Ryanair from Dublin to Glasgow with the flight on Monday at 8:30pm. We will most likely only have carry-ons but it is possible we will check one suitcase. Prior to this we need to return a rental at the Enterprise Dublin Airport location. I am wondering how much time to allow for this process (car return and airport check-in). Don't want to interrupt sight-seeing any earlier than necessary! Thanks in advance.
