Coming out through DUB the other day I noticed a couple of things.
As you exit security you have the wall-mounted Departure Board screens in front of you. Previously, your Gate No. was already up even a couple of hours before your flight but now this has changed and you see that your gate will show only an hour before your flight time. Now, I know this is not unusual but other airports that use this system have a dedicated lounge where everyone waits. There is no such lounge at DUB. So, to recap, pax exiting security see the screens (located in a narrow corridor) showing what time their gate info will appear. It could be gates in the 100, 200 or 300 series. Where are they supposed to wait?
The second point concerns Pier D which is 90% plus for Ryanair pax. About 100 yds into this long walk there is a floor standing sign stating that this walkway is for gates 100 -121 only and pax should CHECK THE GATE NO. ON THEIR BOARDING PASSES before proceeding. Now, when was the last time you saw your gate no. printed on your (home printed) boarding passes?
