You also have to sit a lot of unnecessary up-selling, if you go through an agency. They have rooms of their hotel partners, which are often of poor quality or too expensive, and their tourism activities, which I personally felt to disturb.
So here's what you can do:
First know where you want to go (Asia, Europe, here in Russia, etc., you can be more specific and choose a city)
Second Make sure you get a visa for that country (see list of countries exempt from visa)
Third decide when you want to log out and back (make sure it is your visa validity. If you are employed to ensure that you check with your employer, too. You want to return to your work)
Fourth a budget for your flight (and flight back from Manila to other Asian countries are generally not cost a fortuneespecially if the flight is booked two months in advance. Check online sites such as ensogo promotion agreement and grocery stores, discount tickets)
5th Your credit card and passport next to you that you need to (give some airlines like Cebu Pacific, to allow a counter bank deposit within 24-48 hours for tickets, but most credit cards time are required) Your details
6th make sure you have a reliable Internet connection, like you would not want to waste time re-enter data when the connection fails, as is the case of PLDT
Seventh Care baggage allowance (if you travel light, then you save a lot of money could be used. Are, if you need to take things not forget to bring only the most important in order to avoid paying more fees for overweight luggage. To see forward when you become a frequent flyer program is a generous baggage allowance they give elite flyers)
8th wait for the route Sent and save it to your iPhone instead of printing
You can go directly to the website of the company or you can check online sites for booking flights on travel which is not only cheap but also offer deals for hotels. The best deals, I compare the cost of the transaction directly with the airlines Kayak and Expedia.
Here are some airlines that I have taken:
