What kind of plane is the most spacious and comfortable for traveling in Europe?

Traveling in Europe depends on which city you are going to.

China International Airlines is usually a Boeing 777 or 747. 777 economy class seats are distributed 2/5/2, with 305-440 people. 747 economy class seats 3/4/3, number 3 16-440.

Alitalia is usually a Boeing 747. 747 economy class seats 3/4/3, number 3 16-440.

Lufthansa (LH) is usually a Boeing 747. 747 economy class seats 3/4/3, number 3 16-440.

But if they join a travel agency, they usually choose flights from chartered flight. The flight time and the plane are not ideal. The time is usually night flight, and the model is usually Boeing 737, 737, 730 or Airbus 320, 330. But the front row of this model is also very wide.

When you sign up, you can ask if you can reserve seats on the plane in advance. The aisle seats in the front row are more spacious and comfortable.
