Best Time to Book Flights
Book too early and you overpay the early-bird premium; too late and last-minute fares bite. Pick your trip type to see the ideal booking window — and a few ways to shave more off.
For most domestic trips, roughly 3 weeks to 2 months ahead is the sweet spot — early enough to avoid last-minute spikes, late enough to skip early-bird premiums.
- • Avoid booking within ~2 weeks of departure
- • Mid-week flights are usually cheaper
- • Set an alert and let the price come to you
Why timing matters
Airlines price seats by demand, which rises predictably as departure nears. Domestic fares tend to bottom out a few weeks to a couple of months ahead; international and holiday travel reward booking earlier. Once you know your window, the real skill is catching a dip inside it — which is exactly what a free Planet price watch does. Not sure whether to pull the trigger on a specific fare?

Frequently asked questions
- When is the best time to book a flight?
- For domestic trips, roughly three weeks to a couple of months ahead tends to land the best fares. International trips reward booking earlier — often two to six months out. Peak and holiday travel push those windows earlier still.
- How far in advance should I book international flights?
- As a rule of thumb, two to six months ahead for most international routes, and four to eight months for peak-season or holiday travel, when seats sell out and prices climb.
- Is it cheaper to fly mid-week?
- Often, yes. Tuesday, Wednesday, and Saturday departures are frequently cheaper than Friday and Sunday, when demand peaks. Being flexible by a day or two can meaningfully lower the fare.
