Plane Tickets

     Why is it that when someone tries to buy a plane ticket, the price just doesn't seem reasonable?  It seems like during other dates the prices just seem cheaper or at the very least closer to what one might actually be willing to pay for.  It is almost like it is really unpredictable for someone to find out when plane tickets are going to rise in price making you almost regret wanting to travel or lower in price making it seem like traveling is the best thing to do.  Then once someone does find a cheap ticket, they realize that the price on the airlines website isn't really the true price of the ticket.  One has to take on taxes for the ticket and still add fees to it.  Or if someone goes to an agency they might not be able to really see a visual of what is available and what isn't.
