Practical tips
During high season (summer, winter holidays, long weekends), coaches and flights can fill up quickly. Book your tickets a few weeks in advance to secure your preferred seat class or flight time and avoid disappointment.
For longer coach journeys, opt for 'cama' or 'cama ejecutivo' seats if available. They recline significantly more than 'semi-cama' and often include meals, making overnight travel much more comfortable and restful.
Always double-check your departure terminal or airport on your ticket or booking confirmation. Buenos Aires has several, and going to the wrong one can lead to missed connections and unnecessary stress.
While flights are faster, remember to factor in airport transfer times and security checks. For shorter distances, the total door-to-door travel time might be similar to a coach, but for routes like Buenos Aires to San Luis, flying usually saves significant time.
Bring a small bag with essentials (water, snacks, earplugs, eye mask, a light blanket) for coach trips. Your main luggage will be stored under the bus, so keep valuables and immediate needs with you in the cabin.
