Hi there, $25 from the airport to Panama is the going rate. They charge $10 to antigua. Take into account that its almost a three hours ride. So, that's still a good deal on a shuttle van. So, if you don't want to spend that kind of money then you're going to have to take a chance, first of all paying a cab to take you to the the chicken bus station. And then risking your life with those maniacs driving those buses and also taking a chance getting robbed at the bus station or in the bus. Because they're located in areas which are not safe for foreign tourists to be wandering around because of your valuables, such as cameras, credit cards, etc, etc. So, trying to save a few bucks you'll be risking a whole lot more. Now, for the OP I suggest you make some kind of arrangements with one of the shuttle companies for them to be waiting for all your invites at the airport. www.turansa.com.is also a good company. Good luck.
