Flexibility is key in online ticket purchases
You probably already know this, but there is no harm in going over it again - I’ve been looking recently at getting some cheap airline tickets for a planned vacation in the next few months. There are still some cheap deals available, but they are getting more difficult to find. However, if you stay flexible in terms of dates and timings as well as routes, there are some bargains to be had. For instance, if you are prepared to travel off peak and fly into the less common airports or perhaps use a less well known carrier, you will almost definetely be able to save and keep within your budget. There are many online resources available now that will help you make those decisions - try google as a start.
