To simplify orientation in the terminals, the check-in counters at Cologne Bonn Airport have been renumbered.
A three-digit code replaces the previous letter-number combinations. The check-in counters in Terminal 1 start with a 1 or 2, those in Terminal 2 with a 3 or 4. The naming of arrivals has also been simplified. Arrivals in Terminal 1 are now called Arrivals 1, those in Terminal 2 are now called Arrivals 2 and 3 (formerly East and West). The designations of the gates in the security area and the exit belts on arrival have remained unchanged.
“The new numbering helps passengers to find their way through the terminals quickly and easily as usual. It was very important to us that it was intuitively understandable even for passengers who don't fly often or for whom German is not their native language," explains Airport Manager Thilo Schmid. From March 28, in the two weeks before the Easter holidays, more than 700 signs will be renewed in the terminals, outdoors, at the long-distance bus station and in the airport station. In addition, among other things, site and emergency plans as well as the homepage have been adjusted, and the IT systems have been updated, the airport informs.
