No matter which airport you depart from in London, you will be able to reach it with ease. Should you be departing from Heathrow Airport (LHR), Gatwick Airport (LGW) or London City Airport (LCY), you will be able to take advantage of a hotel the night before your departure so that you are not in a rush the next morning. At LHR and LGW you can also utilise fast track services and lounges before you leave. Whilst this isn’t possible at LCY, it is a good airport to leave from if you are travelling on business as it’s so close to the financial district in London. All the airports have a good selection of currency exchange, food outlets and shops to keep you occupied before take-off too. You will find that there is a larger selection of flights to Ezeiza Airport (EZE) than that of Jorge Newbery Airport (AEP) as this is where most long-haul flights go to in Buenos Aires.

If you are arriving to EZE, then you can reach La Plata in about one hour and 20 minutes driving or Canuelas in approximately 35 minutes by car. In general, it is better to drive to other cities if they are close by as this is faster than taking public transport. Therefore, you could hire a car from the airport terminals to get your journey underway. Alternatively if you are travelling further afield then you might want to consider an internal flight as this will be a convenient way to travel.
