Is there really a flight between these cities?

Yes, but it is rarely worth it. The flight time is about 45 minutes, but adding 2 hours for airport security and the commute to EZE or AEP airports makes it slower than the ferry.

Can I bring my luggage on the ferry?

Yes, standard tickets usually include a carry-on and one checked bag. Check the specific weight limits on your ticket, as they are strictly enforced.

How to travel from Buenos Aires to Montevideo

Skip the flight. You should take the Buquebus or Colonia Express ferry, which takes 2.5 to 3 hours and drops you directly in the city center. Flying is unnecessarily expensive, requires airport transfers, and takes longer once you account for security and check-in.

Choose your ferry company. Compare Buquebus (larger, more amenities, arrives at the main port) and Colonia Express (often cheaper, smaller ships). Both operate from the Dársena Norte terminal in Buenos Aires.
Book your tickets online. Visit the official company website at least 2 weeks in advance. Use your passport number for the booking as it serves as your travel document for immigration.
Handle immigration at the port. Arrive at the terminal 90 minutes before departure. You will pass through both Argentine exit and Uruguayan entry customs simultaneously in one booth at the Buenos Aires terminal.
Board and travel. Board the ferry 30 minutes before departure. Keep your ticket and passport handy for scanning.
