How to know if a cheap flight site is legit
Quick answer
Before paying on an unfamiliar flight site, do six quick checks: verify the BBB rating, confirm HTTPS and secure payment, look up the airline confirmation, read the fare class, review refund policy, and test the customer-service phone.

Most well-known travel sites (Expedia, Booking.com, Kayak, Priceline) are reputable and well-established. The cheap-site-legit question matters when the site is unfamiliar and the price seems unusually low compared to other channels.
Use the checklist below before paying. If the site fails three or more of these checks, do not pay. If it fails one or two, proceed cautiously and pay with a credit card (chargeback protection) — never wire transfer or crypto.
Checklist
Check the BBB rating and online reviews
Look up the site on the Better Business Bureau and Trustpilot. Sites with no online presence or fewer than 50 reviews are higher-risk.
Verify HTTPS and secure payment
The URL should start with HTTPS (lock icon). Payment should accept credit cards, not just wire transfer or crypto.
Look up the airline confirmation within 24 hours
After paying, find the booking on the airline's own site. If it does not appear in 24 hours, escalate immediately — call the third-party first, then the airline.
Read the fare class on the booking
A "cheap" fare often means a strict fare class with non-refundable, non-changeable rules and no checked bag. Make sure the fare-class restrictions match what you expected.
Review the refund and cancellation policy
Reputable sites publish clear refund policies. Vague or missing policies are a red flag. The 24-hour US DOT cancellation rule applies to US-based bookings.
Call the customer-service phone
Test the listed customer-service number before paying. Disconnected numbers, voicemail-only systems, or robotic responses without a human path are reliability concerns.
