Old and not very functional airport for the volume...

Old and not very functional airport for the volume of daily flights. Every day there are delays on all airlines. The screens do not report flight delays until they are already obvious. Landing at the airport involves at least 20 minutes to be able to disembark and at least another 30 minutes to be able to pick up the documented suitcase (almost an hour since the plane touches the ground). There are not enough seats in the waiting rooms. Airport of 4 for a country with ideas of 4th.
