We travelled from Colombo to Abu Dhabi yesterday. On arriving at the airport we were asked for our details and why we had visited Sri Lanka etc and we were pleased with the security in force on entrance to the Airport. However once through to check in this turned into a nightmare. It was nothing but unorganised chaos. We could not check in on arrival maybe we were too early no reason given and we could not understand what was called out and information given on the airport tannoy system could not be understood or even heard. Volume was far too low. People checking in after us were not forming queues but were cluttering up the area and making it impossible for people to check in easily when their flight was called. We have travelled all over the world first time to Colombo and the lack of organisation or any queuing system made it the worst checking in experience ever. It was not until a lady joined the officials on duty that any progress for checking in was made. We were at this airport for 4.5 hours and found it to be the worst system in the world. Once through this area to check in baggage it was acceptable.
