What the letters mean
Rows use the published catalog top speed. This is an editorial grouping so you can see the speed bands. It is not a developer ranking and it ignores capacity, which can matter more for Cash per landing.
S tier
Player decision Use it when the route is Keflavik–Copenhagen and you care about cycle time more than seats.
Player decision Best listed speed per Cash among the supersonic rows.
A tier
Player decision Pick it for the supersonic airliner, not because it is the cheapest way to go fast.
Player decision A Robux alternative if you want speed near the wide-body band without the A380 Cash price.
Player decision Choose it for VIP ramps, not for beating the F-22.
B tier
Player decision Fastest Cash wide-body in the catalog table if you are not buying the supersonic jets.
Player decision The practical wide-body step before the A350 or A380.
C tier
Player decision Do not buy it for the speed tier. Buy it if you want the largest passenger jobs.
Player decision Only if you specifically want the Robux airframe. The Cash A320 matches its catalog speed.
D tier
Player decision Fly it until a Dash 8 or 727 is affordable. It is the right first aircraft, not a late-game earner.
Player decision A light novelty after you already have a job aircraft. It is not a Cash step up from the free King Air.
