I had a nightmarish experience paying Frontier to organise a project for me to participate in. I could write a very lengthy essay on why Frontier are an unfavourable 'company' (yes, I see them as a company, not a 'non-profitable organisation').
As far I am am aware, as soon as I arrived in Costa Rica for my wildlife project, Frontier disowned me and did nothing to make me safe or content in what was a very unfamiliar and scary place to me at first. I paid to stay and help at a wildlife sanctuary where I would sleep in a ranger's hut with other volunteers. However, when I arrived at San Jose airport, my friend and I were taken by two Costa Rican men (one of which did not speak a word of English - he was the guy that drove us) to stay that night with a Costa Rican family who spoke not a word of English either. We had no idea what was going on as this situation was completely the opposite as to what Frontier had described to us and due to the fact that no-one at our destination had explained why such a mistake had been made.
One problem was that we had to find our own way to the Wildlife Sanctuary and once we got to where we were directed, we found that the three of us were expected to sleep in a tiny room in a tiny house in the middle of nowhere with two old women that did not speak any English either and who did not understand us. Bear in mind, Frontier told us that there would be people at the project site that would speak English and we were not told we would need to speak any Spanish. When we hapharzadly stumbled on the guy who owned the 'Tempisque Zoo' we were supposed to be working at when he drove by in his 4x4, he told us that he only takes Biology students on at his zoo who want to learn how to medically treat animals. None of us three were Biology students (the trip was going from bad to worse to hell). Anyway I could go on for ever; there were so many negative aspects to the trip.
As well as my friend and I, there were seven other volunteers that I met that were extremely unhappy about the situation Frontier had put them in. Six out of those seven decided to try to get a flight home immediately. The girl I met before the other six arrived in Costa Rica who was unhappy about the wildlife sanctuary project she had paid to go on also managed to get a flight home but my friend and I couldn't as our flights were 'no-changeable'. So we had to stick it out.
