Unlockable planes after Wash?

I know there was a past thread that kinda explained it, but the comment for after Washington was kinda vague. Can someone explain the bolded part? Is a small plane really the last free unlock? Kinda lame to get 3 smalls and a welfare medium, but one would assume that you would unlock a welfare large/xl the further you get in the game?

The comment in question :
Only aircraft you can unlock in achievements are:

ATR72 at INN
BAe146 at BRI
E190 at PRG
CRJ700 at IAD

You then get aircraft for completing levels, vary based upon airport.

There’s nothing unlockable right now beyond IAD, only the freebies you get by completing certain levels
