Even though I paid for a ticket that included check in baggage and seat assignment, they did not honor the seat assignment and said it was not included. I paid for 6 tickets, 6 bags so I wanted to ensure we sat together for the long flight. I was given the worst seats possible, very last row, next to the bathroom, and a windowless "window seat". Not what I expected when I made the reservation.

The buses can take you anywhere, but it may not be worth the effort to figure out the routes. Buenos Aires is great to walk around – lovely streets, plazas and parks. You can also grab a radio taxi, which is safer than street taxis. You can identify them by the plastic light boxes on their roofs. Make sure you know your destination’s address and cross street, as some drivers don’t know the city very well.
