Local airlines charge twice as much to land at the international airport than they do to land at the municipal airport. When queried about the difference in price we are told that the additional cost is airport "landing fees."
The airport is being expanded and the run way is being extended to accomodate larger aircraft.
When I buy a ticket to go to the US I book on line and ask for a quote with all fees and taxes included - then I don't pay the departure taxes at the airports. The US departure tax was $18 per person (about 7 yrs ago) don't know what it is now.
