There are departures halls in all three terminals: one in the new Terminal 3, another on the Floor 1 of Terminal 2 above the arrivals hall on the ground floor of Terminal 1 which can also be accessed via a slope in the left hand corner of Terminal 2.
There are plenty of free trolleys dotted about and with less passengers carrying hold baggage to be checked in and printing their boarding passes off in advance the queues are not normally that bad, but during the summer months be prepared to wait a bit. With the current security checks it is advisable to get to the airport at least 90 minutes before your scheduled departure time for short haul flights and three hours for long haul.
If you are arriving by bus or taxi they pull up outside the departures area but it is a large terminal and it can be a bit of a long walk to your boarding gate so if you do have mobility problems and need some assistance make sure you leet your airline know at least 48 hours in advance before you travel so that they can arrange for a wheelchair or buggy to be made available to you.
There is a large new shopping area which has all the usual duty free outlets, souvenir shops, fashion goods and newsagents where you can get something to read on the plane.
There is also a good selection of places to get something to eat and drink before you go through security and in the passenger only zone while you are waiting for your flight to be called.
