Hi folks,

I've seen lots of posts about seat configurations and lots of out-of-date calculators, and so on. To rectify this problem, I'm providing my own data on seat selection for you to use.

Based on data I collected, route demand per class consistently follows the following trend:

Y: 86% of total demand

C: 12% of total demand

F: 2% of total demand

That is, on a route with 1000 passengers, you can reasonably expect 860 economy-class passengers, 120 business-class passengers and 20 first-class passengers.

Now, for seat configuration, capacity per aircraft is based on an all-economy configuration. First- and business-class seats take up more space in the following way:

Y: 1 economy seat

C: 1.6 economy seats

F: 2.5 economy seats

Note that these are always rounded **up**, so with a capacity of 100, you can the following example configurations:

0F, 1C, 98Y (total used capacity: 99.4)

0F, 2C, 96Y (total used capacity: 99.2)

1F, 0C, 97Y (total used capacity: 99.5)

This means you can optimize by, for example, placing first-class seats in multiples of 2 and business-class seats in multiples of 5:

0F, 5C, 92Y (total used capacity: 100)

2F, 0C, 95Y (total used capacity: 100)

Therefore to match the number of per-class seats with the amount of per-class demand, we want the following:

86 Y seats with 1 capacity for **86 used capacity.**

12 C seats with 1.6 capacity for **19.2 used capacity.**

2 F seats with 2.5 capacity **5 used capacity.**

So adding this up we have a total capacity of 110.2, so as a percentage of total capacity we have:

Y: ~78.0% of total capacity

C: ~17.4% of total capacity

F: ~4.5% of total capacity

An aircraft with a capacity of 551 would perfectly match these requirements and have an ideal seating arrangement.

Based on this data, the following configurations are within 1% of the ideal ratios:**164-166 cap:** 128-130Y 18C 3F**219-222 cap:** 171-173Y 24C 4F**328-333 cap:** 256-260Y 36C 6F**437-443 cap: **341-346Y 48C 8F**546-556 cap: **426-434Y 60C 10F**601-602 cap: **469-470Y 65C 11F**604-612 cap: **471-478Y 66C 11F**655-658 cap: **511-514Y 71C 12F**659-667 cap: **514-521Y 72C 12F_{(Note that I have removed ranges for which there are no applicable aircraft in-game)}

In general, in terms of the maximum available seats in an all-economy configuration, the number of seats per class as a percentage of this maximum are:

Y: 78.04%

C: 10.89%

F: 1.81%_{(Note that these do not add up to 100% because of the capacity losses from first- and business-class seats)}

So to calculate the number of seats you should assign, take the total capacity * A* stated in-game and do the following:

Y seats = [ 0.780399274 ×

*]*

**A**C seats = [ 0.108892922 ×

*]*

**A**F seats = [ 0.01814882 ×

*]*

**A**where [

*x*] is

*x*rounded to the nearest integer.

I have attached a spreadsheet with the ideal configuration for every capacity up to 853, the A380-800.

I'd be happy to answer any questions you may have.
