A look at the advisories on the internet for getting cheap air tickets would show you that one most common advice is that of having a flexible time schedule for travel. This essentially means that you shall be prepared for doing the flight booking for some other day or time and organizing your travel schedule with this scope for flexibility. While this is definitely a good idea to go about doing it, there is certainly some limit to this flexibility, which you would often find difficult to utilize to your advantage.
If you are going on vacations with your family after taking a break from your work, this flexibility is limited to the date to which your vacations would extend. This means that the search for the cheap air tickets, even when you retain the flexibility of travel, is rather limited and therefore, the best deals that you can get are also limited within the scope of certain specific time frame only. The airlines are well aware of this limitation and, therefore, while there could be some fluctuations in the rates, these might not be too appreciable to make any substantial difference to your savings on flight booking.
The people, who consider this as a good means of getting cheap air tickets, shall reconsider their strategy and shall also include some other ways and means to get low cost flights. They can make use of their reward points to get some free miles, if that option is feasible to exercise. If the travel dates are not going to change, then booking the non-refundable tickets would be another good idea for getting the low cost tickets. If it is not possible to change the day, then you can think in terms of flying at the non-peak hours when there can be a chance to get the low priced tickets. While making the flight booking on a round trip, if you cannot be flexible in getting good deals while traveling on any one leg, you can always explore the feasibility of being flexible in day and time of travel on the other legs of the journey for saving some money.
Since airline ticket pricing is quite dynamic and the airlines are restrained majorly by competition levels and the demand factor for flight tickets, the negotiations on discounts is rather a futile and time wasting method. However, if you can club the flights with some other travel product such as hotels, cabs or sightseeing packages, then there can be more discounts to be availed on overall costs that are a more significant saving.
