Last month, I tested 15 major flight booking platforms using the same route (Lagos to Dubai) and found price differences of over ₦85,000 between the cheapest and most expensive options. After booking hundreds of flights through various platforms over the past year, I’ve discovered which sites actually deliver on their promises and which ones will leave you frustrated with hidden fees.

The truth about flight booking sites isn’t what most travel blogs tell you. Some “discount” platforms add fees at checkout that make them more expensive than booking directly with airlines. Others show fake “limited time” deals to pressure you into quick decisions.

This comprehensive guide reveals which booking platforms genuinely save money, which ones to avoid, and the exact strategies I use to find flights up to 70% cheaper than standard prices.

Frequently Asked Questions

Which flight booking site has the lowest fees? Aviasales consistently has no booking fees, while most others charge ₦1,500-8,000 in additional fees. Always check the final price before payment confirmation.

Are flight prices different on mobile vs desktop? Sometimes. Airlines and booking sites may show different prices based on your device. Always check both mobile and desktop, and clear cookies between searches.

Should I book flights and hotels together or separately? Usually separately. Flight + hotel packages rarely offer genuine savings and reduce flexibility. Book flights first, then find hotels independently for better rates.

How far in advance should I book international flights? For best prices, book international flights 2-8 months ahead. Peak season routes (December, summer) should be booked 4-6 months early.

What’s the best day of the week to book flights? Tuesday at 3 PM local time statistically offers the lowest prices. Avoid booking on Fridays and weekends when airlines raise prices.

Can I trust third-party booking sites with my payment information? Stick to established platforms like Aviasales, Skyscanner, and Expedia. Avoid unknown sites with prices significantly below market rates.
