What is the difference between Business and First Class cabins?

As with all cabin classifications, ch-aviation applies a consistent and standardised methodology to distinguish between Business Class (C) and First Class (F), ensuring comparability across all carriers and aircraft types worldwide.

The classification is based on the maximum number of seats per row (Max Abreast) as follows:

• Narrowbody aircraft – A cabin is classified as First Class only if the maximum number of seats per row is 2.
• Widebody aircraft – A cabin is classified as First Class only if the maximum number of seats per row is 4.

There is one exception to this rule: in cases where an aircraft has both a Business Class and a First Class cabin installed, the First Class cabin may have more than 4 seats across per row and will still be classified as First Class accordingly.

Any cabin that does not meet these thresholds will be classified as Business Class, ensuring that the First Class designation is only applied where a genuinely elevated level of space and configuration is present.
