Search & Book
This deal does not have an expiration date, but a minimum stay of a Saturday overnight stay, and a maximum stay of two months apply. Departures from Madrid are scattered from January through June and from September to December 2026. The route from Barcelona starts in April.
You can find suitable dates using our calendar above or with the help of Google Flights. We recommend booking directly on Cathay Pacific’s website, but you can find cheaper prices with trip.com. However, booking on OTAs has its downsides.
Why is booking with an airline better than with an online travel agency?
More often than not, online travel agencies offer lower fares than airlines do. We still recommend booking with the airlines directly. There are two main reasons for that:
Better Customer Service
In case any problems like delays, cancellations or missed connections arise, you can communicate directly with the airline. The airline has to take care of you because you have a contract with them.
If a travel agency issues your ticket, you may have to reach out to them first. You also depend on your OTA to forward information like flight changes instead of receiving them directly from the airline. In many cases, you may get a prime exhibition of responsibility shifting rather than problem-solving.
This especially applies to premium tickets. You don’t want to spend more than €1,000 to wind up with some budget OTA’s telephone hotline in case anything goes wrong.
Baggage and Other Fees
Economy fares not including hold luggage are industry standard by now. In most cases, travel agencies charge much higher baggage fees than the airlines themselves. If bags are not included in your fare, airlines are often the cheaper alternative.
This also applies to other things like food services, insurances or priority treatment. In almost all cases, you pay less for additional amenities when booking on the airlines’ website.
Editor’s Note: Flying 5-star Cathay Pacific to Thailand for €499 is an incredible price. Since luggage is included, this is easily one of the best offers we’ve seen from Spain to Asia recently. Perfect for a winter escape in 2026!
