It's easy to use so there aren't any problems in using it for me as an airport manager at Luton Airport this was my first time trying ETI but now I'm pleased that we decided to go down this route because everything went very smoothly from start to finish! There are not many other airports who have such great customer service like you guys do over here which makes our lives easier when managing things during rush hour etc.. Nothing really dislikes about electronic travel information systems however maybe just try new features or think of more ways they can improve their services by adding different options/features? We've seen how much better your support team has gotten since coming into contact with them previously through email regarding questions I had asked before purchasing Eti systems.
