If you have to be at your destination by a particular time, be careful about waiting too close to your departure time before purchasing your ticket. If you do not have your seat reserved a week before you need to be there you run the risk of not being able to get a flight. This is especially true of flights to popular destinations and during peak travel season.
There are many ways to go about getting airline ticket
Typically, booking a whole trip with different airlines would be risky. For example, let's say your first flight with JetBlue was delayed, and you missed your connecting flight with Norwegian Air. Because the airlines have no association with each other, Norwegian Air has no obligation to reschedule your flight for free, so you would just lose your money. Kiwi.com instead offers their own guarantee, which covers schedule changes, flight delays, and cancellations. As long as you contact Kiwi.com as soon as you're aware of the delay, they will provide you with an alternate connecting flight, or a full refund, at your discretion. We haven't used this guarantee ourselves, but it certainly sounds like an appealing way to take the risk out of a thrifty flight hack!
Although it is arguably quite tough to save up enough miles to get a free flight, using the miles that you've accumulated to offset ticket prices or upgrade seats can still help you save some serious money. Taking advantage of the bonus offers you get when you sign up for top travel credit cards is definitely the easiest way to collect enough miles for 100% free flights.
Vacations aren’t cheap so you might want to find everything
also some ways that people tend to forget about like using
While the above search engines are great, they do not always include small airlines, especially in less popularly booked routes and/or in remote regions. If you're flying somewhere obscure, Google search and ask around if there exists a local airline. While in South America we learnt that the LADE Air in Argentina (run by the military) has cheap flights to Patagonia, which is of course not listed in mass search engines online.
First, do your research: are there budget airlines unique to the country you're flying out of and where you're headed to? Booking with a budget Australian airline (Jetstar) from Sydney to Honolulu, then an American one from Honolulu to Montreal saved us over $400 each when flying back from Australia to Canada earlier this year. This allowed us to create a thrifty five-day stopover in Hawaii on our way back, which was less exhausting and a lot cheaper! Kiwi.com and AirWander are both great search engine for revealing cheaper routes like this that involve multiple airlines.
