Flight Resources

I use Kayak and Expedia for flight booking.

From The Road is Life blog she uses Momondo and SkyScanner for flights.

Flying with no return ticket: This article shows that there can be problems flying on a one way ticket with no return. This is an issue with airlines not necessarily with the immigration rules of the destination country because if you were to be refused entry then the airline is obliged to immediately fly you back to your home country – at their cost.

A regular traveller suggests getting to the airport early in case there are issues. Sometimes merely explaining to the agent why you are flying without a return ticket is sufficient.

Another solution is to book a refundable return ticket and refund it as soon as you arrive at your destination. Or you could book a flight that will be used part way through your travels. As the article notes: "Keep in mind the goal is just to show you can leave the destination country. You don’t need a return ticket all the way home, it can be enough just to have a flight to a neighboring country."

Another possible solution is to use a service called Onward Ticket. This service books an actual flight reservation and provides a document indicating all the details of the booking. You receive the document in 2 minutes! The booking is held for 48 hours and then cancelled unless you contact them to hold the reservation. Cost is from $14 USD.
