I’ve used Bags and Co multiple times from airport to ship and ship to airport.
The last time I used it was September 2023. They are available outside every berth as soon as you pass Passport Control and customs.
You can pre-book on their website if you wish which allows you to drop and go rather than queue.
The cost is 12 euro for the first bag and 10 euro for each subsequent bag. They will take your bags to the lower level of Terminal 1 for you to pick up (irrespective of which terminal you depart from). The latest pick up is approx 7pm so you will need to get your bags by then.
It’s a fantastic service - I’ve used them and recommended them so much I’m going to ask for a freebie when I’m at Barcelona port in May! 😀
