Andesmar and Via Bariloche both provide excellent services

Are these buses typically on time..Is it ok to have a window of about 1.5 hr to make a flight connection?? For eg. I am planning to take a 11.15 pm bus from Bariloche which reaches Neuquen @ 5.05 am from where I have a connecting flight to Buenos Aires @ 6.35 am?? The flight to BA reaches @8.15 am after which I have a flight from BA to Iguazu @10.20 am. Does anyone know the location of the Bus station in Neuquen and if it is close to the airport or not??

Good luck!

Our experiences with the buses we took is that they generally ran on time. we had one maybe 15 minutes late leaving. that said, we had a friend who's bus encountered problems and they were several hours late arriving. this was in NW ARG.

sorry can't help with the location of the bus station.

Soory but can't help about the location of the bus station but the timing to get your flight does seem tight (but possible). That said the chances that you bus will arrive on time are probably much higher than your flight leaving on time!! All the buses we took in SA (a lot!) arrived within 15 mins. Our bus from Puerto Madryn to San Rafael in Mendoza province departed 90mins late but still arrived on time (20 hour journey time)
