Right now, I feel like the seat configurations for wide-body aircraft is just way off. With an A330-300 in the game, one can have well over 300 economy seats with several first class seats and around 30-50 business as well. This is just unrealistic. Thomas Cook in real life only have 326 economy seats in an all economy layout while other full service airlines have around 130-170 economy in a three class config or 200-250 in a two class config. It's just an unrealistic payload to have over 300 economy seats with a two or three class config.
I honestly feel like, for this game, the first class seats and business class seats take up the same amount of space, no matter what aircraft they are on. IRL this is simply not true as long-haul seats for first and business are turning into suites with seats that go fully flat for sleeping and on narrow-body aircraft, the seats are simply wider and have more legroom. Something needs to be adjusted to increase the amount of space first and business class seats take up on the bigger wide-body aircraft.
