People are always asking for free travels but for the matter of fact,
there is NOTHING Free...
Keep that in mind but there are things that airline think that are valuable that YOU actually have.
so you need some tips for cheaper travels? here you go
1) Meeting even code
Let start with a more side tracked ones, Airline always offer Meeting event code to events that have partnership with them to offer 5% to 15% off ticket depending on booking class!
if you are flying to big cities like New York, Chicago, San Francisco, Los Angeles,
this is for you! but it takes time to search it but often you can Google and find some.
2) Search, Search and Search...
One thing about searching engines, it's not always the cheapest ways!
it may be the easiest but it's NOT the easiest way to do it!
for example, KAYAK.com
you can search serial airlines especially for international travels
after you search the cheapest airlines, do the search again on the lowest 3 airlines webpage so that you can find the real deal!
Airline like Delta always have a slightly better deal on their own webpage AND sometimes a better flight time or connections! Keep in mind and do that, sometimes, it can be very unexpected.
ofcoz the same time RyanAir or some budget airline aren't searchable in the searching engine as well
