If you’re flying somewhere that involves a transfer, say from Canada to Australia which typically involves Canada to LA, then LA to Australia, consider that it may be cheaper to book these two legs separately on your own by adding another destination to your trip. It should go without saying that in doing this, you should not book tight layovers. I repeat: do not book layovers that are hours apart! This approach is for those who want to create an additional destination of a few days or more, before catching their next flight. The one exception is when booking with Kiwi.com, who offer their own guarantee on making connecting flights even when not with the same partner airlines.
For domestic travel, buy your ticket three months before your departure date; for trans-Atlantic travel, buy five months beforehand. Any further in advance has no benefit, according to Mr. Seaney, because airlines have not yet included cheap seats as part of their inventory. But be sure to buy 30 days before departure because prices increase substantially thereafter. The exception to this rule is if you plan to travel over a busy holiday period, especially Thanksgiving and Christmas. Airlines don’t offer discounts during the holidays, so it’s best to buy your ticket as soon as possible.
Nobody likes junk mail, but getting on email lists for your local teams and venues (or in other markets with which you have good familiarity) is the best way to find out about hot new concert presale events and discounts. Another benefit of being in the points/miles hobby is that often times Citi and American Express cardholders get special presale access (and sometimes discounted prices) to events.
