It has been a few years since I have been in Costa Rica, and would like your opinion, or recommendations on what airline to use from San Jose to Golfito for a trip in late July, or early August. Cost is a big factor, and any help would really be appreciated. There will be four of us, we always travel light, so baggage weight isn't an issue, and getting to and from airports isn't an issue either. Looking for a reliable, low cost airline. Thank you.
