Well, I’m back from my travels and thought that I would share my experiences with others who might find the information useful.
So yes, I did need proof of onward travel whilst checking in at Mexico City for the Copa Airlines Mexico City – Panama City flight. They seemed pretty thorough with this too, as some other passengers were frantically explaining their onward travel plans to convince the Copa check in staff. They definitely seemed like they wouldn’t put up with any nonsense.
I got around the onward travel proof by making an online ‘reservation’ with expedia for a Panama City – San Jose ticket, but just printed out an itinerary of the flight details with my name highlighted before the purchase ticket stage. This looked like an online ticket, especially with the ads and logos around the flight details. Now, I know this was risky, and it did appear that she looking for my onward flight details for about 15 or so seconds, but eventually she just gave the printout back and advised me that I would need proof of onward travel when entering Costa Rica. Relief, but I’m not sure how close I was to being found out. As for immigration itself in Panama City, it was a doddle. I was asked what the purpose of my trip was and then had my passport stamped and then I proceeded through. So it seems that the airline check in process is far more thorough and travellers really do need proof of onward travel when flying into Panama.
I should also point out that Costa Rican immigration was very thorough too, and demanded proof of onward travel. Again, I produced a ‘reservation’, this time a Tica Bus ticket that I put together before leaving Mexico. I was fine, but my friend was quizzed as to how she bought the ticket. No delays though and we were let through. It seems as though Costa Rica is pretty thorough, and many travel agencies that we saw throughout Central America were warning travellers of the fact that onward travel proof was needed when entering Costa Rica, and some agencies would refuse outright to sell tickets to Costa Rica if customers didn’t have onward travel plans. Before leaving, I got the impression from reading forums that Costa Rican immigration might be pot luck, but seems as though they’re enforcing this requirement quite rigorously.
As far the rest of Central America, no problem. Obviously things change quickly in this region, but I hope some of the info is helpful.
