My experience is that it is not just the signage that is a mess, but because the gate allocation is relatively short to the departure time of the incoming aircraft, it is stressful to make sure you get there ... especially in the case of Ryanair flights from their terminal because they close the gate at departure time -30 mins, and the gate only shows up at departure time -40 mins. Of course, you can try to beat the system by going to the Ryanair wing 'early' and hoping that your flight will depart from there, with a relatively quiet café and plenty of seating ... but if you get it wrong, it's like the Grand National to get back to the departure lounge and start again on a transit ....
