If you are traveling to/from Buenos Aires central, I highly recommend that you take the ferry over the plane. If you book on Buquebus or BQB, the cost will be about the same as the high speed ferry.
Honestly speaking, by the time you add the travel times the ferry is much faster and simplifies your travel by leaving from the center and arriving in the center.
It takes an hour to Carrasco airport from downtown Montevideo, then 1~2hrs check in and security, then 45 minutes flight (if it is not delayed), then 30 minutes to clear customs, and another hour from Ezeiza airport to downtown Buenos Aires. That totals about 5 hours. And you also have to add the cost of airport transfers.
The fast ferry takes 3 hours and eliminates the time and cost of airport transfers.
If however you are transferring internationally, then by all means taking the flight option is a much better idea.
We booked this flight online....Note if you boook several flights at the same timethe savings are substantial.
We had a comfortable flight but they only allow 5kg hand luggage so we had to check our bags...first time.
We couldn't believe we got a juice box and a snack on a 30 minute flight!!
Left Montevideo for Sao Paolo by plane, on Pluna airlines.
Airport is a taxi ride from town (500 peso dec 2010)
Very modern terminal building with fast and efficient check in and the usual array of shopping opportunities once through security.
Be aware that there is a departure tax, $35 US (dec 2010) payable by card if you've no cash. Rates differ for Uruguayan nationals and for internal flights.
You can come to Montevideo by plane; the Carrasco International Airport is not situated in Montevideo, but it is quite close; there are some international flight that arrives here directly , but most of them have connections with Buenos Aires (Argentina) or Sao Paulo (Brazil).
Pueden venir a Montevideo en avión; el Aeropuerto Internacional de Carrasco no está situado en Montevideo, pero se encuentra muy cerca; algunos vuelon internacionales llegan aquí directamente, pero la mayoría hacen conexión con Buenos Aires (Argentina) o Sao Paulo (Brasil).
Well, the gateway to South America when you are this far south, for US passengers, is frankly Buenos Aires.... so many flights will fly you to BA, and then will go onward to MVD. Such is the case for me. I chose to continue on the UA flight that landed MIA- EZE, and then EZE - MVD.
The flight one way, EZE-MVD, was $68.00USD. Worth it... because the one way Ferry ride is the same, but since I would have had to take time / money to commute to Port, it was cheaper, shorter to fly from EZE....
Quick flight too.... and the Airport at MVD is small and managible even if you don't speak Spanish.
