Kotakota, I agree that work is needed but remember that up until now CAI caters for point to point travel. In fact in 2006 (2007 figures not yet finalised) only 1.4% of passengers using the airport were transiting the facility, so the infrastructure is not designed to handle this type of traffic. Furthermore remember that the airport is operating over its design capacity which only makes operations even more difficult. T1 was overhauled a few years back and once T3 opens, T2 will be rennovated and connected to T3 with an air bridge. MS are already seeking an extention of T3 as the airline expects a rapid growth in flights/passengers with its new business model.
With MS planning to develop a true hub & spoke operation at CAI (currently its arguably just a base) and with the full backing of the ECAA, CAC and Fraport one should see an overhaul of operations.
