They don't have a hook, they are experiencing the same problems as anyone. On Thursday a package arrived in Miami, normally I have it on Monday in my possession, now I'll have it tomorrow. I called them this afternoon and asked them why it says for three days that it's in 'aerolinea'. They told me that means it's not in aerolinea but already in customs. Only when customs start proceedings with my package they will change the status. That makes sense, because the status 'en aduanas' doesn't last longer than half a day.
Eps is the best though. Never lost any package, never a problem. A little bit more expensive, but good service.
