We are taking a 3-week trip and planning to fly into Panama City and out of San Jose, Costa Rica. I have read that upon arrival into Panama you must show a return ticket out of Panama. I travel a lot and I know that most countries have this "rule", but it is not often enforced. What is the case with Panama? If this is enforced at the airport, how can we get around it? Our departure out of Panama will likely be by bus into Costa Rica on the Caribbean side.
