5. Negotiate with a travel agent : It's true that online flight deals can help you save big on flight tickets, but there is also a high chance that a travel agent can find a better deal for you. Call center representatives have options to waive a few charges and customize the deal (to fulfill the sales target of course!). All you need to do is to be patient while calling and you may land up getting an enticing airfare deal.
Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you flights up to 3 days before/after your preferred dates. That way, you can see if leaving a day or two earlier will find you a better deal. You can also select the flexible "weekend" or "month" search options to widen your search range and find the cheapest price that works for you.
