Very hard on baggage (Be careful with “cabin baggage” as it might need to be checked-in, not brought on the aeroplane, depending on what is written in the small print on the tickets. Usually arrive a bit earlier than written on the website.

The Swedish equivalent of Aer Lingus, quite lenient with baggage, printing out boarding passes etc. Usually arrives a bit later than written on the website, but with free tea/coffee onboard.

Norwegian strikes a balance between the two, offering 30 minutes of free Wi-Fi. Choose your airline based on your preferences for comfort and flexibility.
The fastest way from Arlanda Airport is by train. The difference in price means that the extra time it takes travelling by bus is usually not worth the savings when buying a ticket.
To get to the trains you have to make your way to “Terminal 5”/”Sky city”, look for the round ticket office beside the big windows, and make your way down the escalators to the train platforms.
The train platform is basically an underground station, a bit colder than the airport, with limited facilities, (toilets and a couple of vending machines).
Trains in Sweden are nearly always on time, and if they come to the station early they wait until the departure time before leaving the platform. It takes about 10 minutes to get from “terminal 5” to the underground platform.
Stockholm is 20 minutes away from Arlanda regardless of which train is taken, so choose the one with best price if travelling there. Trains can be booked on the SJ website:
There are two types of trains that run, a “commuter” train, that basically looks like a big subway train, (cheapest option), and run by “SL (subway)” or “malartåg”
The other type of train is “normal” trains run by “SJ”. They are bigger trains, sometimes two stories, usually more comfortable and more expensive. From Arlanda to Stockholm both options take roughly the same time.
If travelling to Gävle the best option is to take “SJ”. Their high-speed trains take about an hour from Arlanda to Gävle and are very comfortable. There is also the option of traveling with “mälartåg” (https://www.malartag.se/) which is cheaper, but takes 1 hr, 40 minutes and involves changing trains halfway through. (changing trains is relatively simple and they are usually on the same platform, but if the SJ tickets are booked in advance there is not much difference in cost, and you avoid an extra 40 minutes on the train.) Gävle is the city where we live, and has all the shops/pubs/restaurants etc.
If travelling from Arlanda, or Stockholm, to the wedding venue the best option is a combination of the two trains, which usually comes up automatically if you search on the SJ website
