[EN] If travelling from abroad, a flight to Paris airport Charles-de-Gaulle (CDG) is by far the most convenient. From there, you can directly take a bullet train: the trip only lasts around 2 hours and gets you right in Strasbourg city centre!
You may also take a flight that gets you straight to Strasbourg airport (SXB). From there, the fastest way to get to the city centre is by train, which takes 12min and costs around 4€. You can also take a taxi, which should cost around 30€ to the city centre.
