Welcome to FT, travelvlogger!
The best place to get started is to read the RESOURCES threads at the top of this forum. Getting Started would be a good place to begin. You may find the information a little overwhelming but bear with it. FT is not a site that helps people with finding low fares, you should look at kayak.com or google.com/flights. If you only travel twice a year, don't worry too much about collecting miles (don't buy expensive fares that earn more miles) because you'll need a lot of flights to have enough miles to really do anything useful.
