Why are the united states but in french without article les
"Les" is in the drop-down hints. Until I saw it there, I was not going to use it. This is doubly annoying, because I rarely use the hints at all, now that my "feel" for the language is building up.
Why not Ces vols vont aux États-Unis?
What is the difference between vols and avions?
→ These planes
→ These flights
Ces avions parteront au les etats unis. Marked wrong. I suppose the difference is that the planes mentioned in the sentence given us are in the air and not on the ground.
To leave for + precise destination = Partir pour + precise destination.
Ces avions partent pour les États-Unis.
Yet, this sentence has "are going to" = Ces avions vont aux États-Unis, where "aux" is the contraction of "à+les".
