Question: what is the difference between 1st and 2nd class on tgv?
Answer: The seating layout should be pretty similar for the Paris - Avignon train. Generally on trains, in second class there are four seats across the width of the train, and in first class there are three. The space between the seats is also bigger. For an extra 50% in the fare, you therefore get about 10% to 20% more space.
