Frequently Asked Questions

How far in advance should I book a domestic flight?

For US domestic flights, the sweet spot is 1–3 months before departure. Booking too early (6+ months) or too late (under 2 weeks) typically results in higher prices. The cheapest domestic fares appear 47–60 days before departure on average.

How far in advance should I book an international flight?

For international flights, book 2–8 months in advance. Transatlantic flights are cheapest 2–3 months out, while flights to Asia and Oceania are best booked 4–6 months ahead. Consolidator fares through Camli are often available even closer to departure.

What is the cheapest day of the week to fly?

Tuesday and Wednesday are consistently the cheapest days to fly domestically. For international flights, weekday departures (Tuesday–Thursday) are typically 15–25% cheaper than Friday–Sunday departures.

What is the cheapest month to fly?

January (after the 7th), February, and September are the cheapest months for most routes. These shoulder/off-peak periods see the lowest demand and therefore the lowest fares. Avoid June–August and December for the best prices.

Is it cheaper to book flights on Tuesday?

The myth that airlines release sales on Tuesdays is largely outdated. Modern airline pricing is algorithmic and changes constantly. However, flying on Tuesdays is still cheaper because demand is lower on that day.

Do flight prices go down closer to departure?

Generally no — prices increase as departure approaches due to rising demand from business travelers. The exception is consolidator fares, which may become available close to departure as airlines try to fill remaining seats through wholesale channels.

What time of day are flights cheapest?

Early morning flights (before 7 AM) and late-night red-eye flights are typically the cheapest. Mid-morning and early evening flights command premium prices due to higher demand from business travelers.

How can I get the cheapest flights regardless of timing?

Use consolidator fares through Camli. Unlike published fares that fluctuate with demand, consolidator fares are pre-negotiated wholesale rates that can save 20–70% regardless of when you book. Call +1-(855)-919-6470 for a free quote.
