If you are planning on taking a year out and not sure of the exact date when you will return you will naturally seek out a return flight but with the return date flexible and open. Although this option does seem available with some airlines would appear you have to pay for the flexibility. Generally you cant book an open return ticket on the internet flight portals, it is something your local travel agent can potentially sort out for you. High street travel agents may still have their uses.
Another option is a one way flight and then buying a return ticket when you know the date you want to come home. Most countries can refuse entry if you dont have a proof of a flight out of the country. Although this is not commonly enforced. Even a train ticket out of the country will not suffice is some situations. Checks are more frequent if you are coming from a poor country into a rich country.
Seems the best option may be to book a return flight way off into the future roundabout when you think you are likely to return. You can then pay an extra fee with the airline to change the date to something more precise, this may range from 0 to $150 taking peak bookings into consideration. The most you can set your future return is one year, if you go over the year then your ticket is void and you have to rebook.
Currently I am debating if to go down the student visa route or just hanging around for 30 days on my tourist visa and travelling between Thailand, Cambodia and the Philippines and maybe some other countries around south east Asia.
Anyone with any experience on these travel matters, would appreciate your comments on the subject….
