Trip.com’s September sale includes £29 return flights from London to Barcelona, Madrid and Milan from 9 September, with Rome at £39 and Paris at £49. The fares are part of an app-only flash sale, and there are only 50 returns shared across the European routes, so this is one for flexible city-break planners rather than anyone who needs a fixed date.
The sale itself starts today and runs through 11 September. The flight flash sale opens at 9pm on Wednesday 9 September and runs until 8.59am the following morning, with selected travel dates between 11 September and 31 December.
The £29 flight release
Trip.com lists £29 return tickets from London to Barcelona, Madrid and Milan, plus Rome at £39 and Paris at £49. Those fares are limited to 50 returns across the European routes and are sold through the Trip.com app during the overnight flash sale.
The published travel window is 11 September to 31 December. The fares do not include baggage or seats, so price up the trip with the extras you actually need before paying.
What else is in the September sale
The wider Chase the Sun campaign has more than the flight release. Trip.com is advertising up to £50 off selected flights and hotels, hotel discounts for selected city stays, and train offers including a £36 Eurostar flash sale. There are also limited railcard and selected UK train offers, so it is worth checking the relevant tab rather than assuming the flight deal is the only one.
How to book
Open Trip.com’s September sale page, then use the app for the flight flash sale from 9pm on 9 September. Be signed in before the release, select the route and dates you want, and check the final fare and any extras before paying. The cheapest tickets are limited and availability can disappear quickly.
