How to save on flights: the tricks that actually work
Flights are often the most expensive (and most unpredictable) part of a trip. There's no magic trick, but a combination of habits that together can make a real difference to the final price.
When to book (and when not to)
For international flights, the optimal window is generally 2 to 4 months before departure; for domestic or European flights, even 3-6 weeks can be enough. Booking too early or too late tends to cost more.
Avoid booking at the last minute unless it's an emergency: it's almost always the most expensive option, aside from rare last-minute deals on low-demand routes.
Being flexible on dates and airports
Shifting departure by even a single day, or considering an alternative airport in the same area, can noticeably lower the price. Tuesdays and Wednesdays are often (not always) the cheapest days to fly.
Use the 'price calendar' view on flight comparison sites to spot the cheapest days in a month at a glance.
Flight comparison sites: how to use them well
A comparison site aggregates fares from multiple airlines and agencies in a single search, but it's also useful for setting a price alert on a specific route and getting notified when it drops.
Always compare the final price, including the baggage you actually need: a seemingly cheaper flight can end up costing more once you add checked luggage.
Layovers, low-cost carriers and other trade-offs
A flight with one layover almost always costs less than a direct one, provided you have time to spare and check that the connection is reasonable (same airport, sensible layover time).
Low-cost carriers can save a lot on the base fare, but watch out for extra costs (baggage, seat selection, payment fees): always calculate the real total price.
Loyalty programmes and payment cards
Signing up for the frequent flyer programmes of airlines you use most often costs nothing and builds up useful miles over time, even for occasional flyers.
Some credit cards offer points or cashback specifically on travel purchases: if you fly often, it's worth considering, but only if the card's annual cost is covered by the benefits you actually use.
Common mistakes to avoid
Looking only at the ticket price without factoring in baggage, seat selection and other extras is the most common mistake with low-cost carriers: the final price can be very different from what's shown on the front page.
Waiting for 'the perfect moment' to book, constantly putting it off hoping for a lower price, often backfires: once the optimal window has passed, prices tend to rise, not fall.
