You then go up to BP scan, security, and exit migraciones. I have no idea how bad it gets at Terminal C. I can tell you that at A in the evening, you need to budget an hour (it can take more, but rarely).

You then have a decent walk out to the AR (Aerolineas Argentinas) lounge, and your departure gate can be a decent walk from the lounge (or very close). All the international departure gates are connected, whether you enter @ A or C.

By leaving aroubnd 4.30 pm you miss the worst of the rush hour.

Immigration at Terminal C shouldn't be an issue since there are not many flights leaving close to DL's - AF, AZ and KL have all left and AR widebodies only take off after 11pm.
