As a senior, travel is a great way to rejuvenate and relax. It also keeps you mentally agile and young at heart. The good news: Airlines across the industry offer seniors low flight rates. The bad news: Finding cheap flights as a senior can be confusing. Here is all you need to know about seeking out cost-effective travel deals and flight tickets.

The first thing to understand is that there is no one-size-fits-all solution to cheap airfare. Benefits, as well as minimum age requirements, vary from airline to airline. Some airlines offer discounts to adults over 55, while others might have a minimum age requirement of 60 or 62. It’s always a good idea to check with the airline and find out if you qualify for a senior discount.

Another question that most seniors have is where to start looking for cheap flights. While many third-party websites do offer low airfare, you want to frequent websites that also make decision-making less painful. A few websites contain travel tools, additional information, and special deals for seniors in addition to cheap flights. This amounts to a world of benefits when it comes to cost-effective air travel. We’ve listed three of these websites here.

Kayak: Kayak doesn’t just stop at providing you with airline ticket deals. It also has information about hotels, travel packages, and rental cars. Its interface is easy to follow and understand and they have a “hacker fare” feature that combines one-way trips from various airlines to get you an unbeatable deal.

Travelzoo: The great thing about looking for cheap airline tickets on Travelzoo is that you don’t have to keep actively searching their database. Sign up and the site emails deals to you. If you do visit their site, use the SuperSearch feature to compare price points across airlines.

CheapOair: This site has a Best Price Guarantee feature, which promises a full refund if you find a lower fare on another travel website within 24 hours of booking. It also offers 10 percent discounts on select flights and has a host of other travel-related information.
