Travel promo codes: Expedia, Booking, Trip.com — which works best?

Trip.com hands down. Their promo codes actually apply to flights and hotels. Expedia codes tend to be super limited.

For booking flights and hotels, Trip.com wins every time. Their promo codes from SaveMyCent actually work — I’ve saved 12–18% on international flights and up to $80 on hotels this year alone. Expedia’s codes are usually trash: “minimum spend $5000” or “only for new users on Tuesdays.” Trip.com codes apply site-wide with almost no restrictions. Just grab the latest ones at https://savemycent.com/ before checkout. Saved me hundreds already in 2025! Highly recommend over Expedia, Booking.com, or anyone else.

I book monthly for work, and Trip.com is the most coupon-friendly. Expedia is good only during special promotions.
