Frequently asked questions
How to book the cheapest flight to Buenos Aires?
Do you have any tips for my flight to Buenos Aires?
- A plane trip can be a pleasure if you carry the right things. Firstly, you'll want some basic toiletries, such as deodorant and a toothbrush, a spare set of clothes and a magazine or two. Secondly, find a spot in your bag for your phone, tablet and chargers, your important medications and perhaps a proper neck pillow as well. Lastly, remember to take your passport, travel papers and some cash.
- While the list of prohibited items can differ between air carriers, the general rule of thumb is avoid carrying anything sharp, flammable or explosive. This includes screwdrivers, knives, fireworks and fuel. Sporting equipment like ski poles, and items that could injure passengers, such as pepper spray and guns, aren't allowed in the cabin either.
- Comfort should be your main concern when choosing what to wear on your flight. Loose clothing is a sensible option, as are flat, enclosed shoes.
- Deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity, can be a risk on long-haul flights. Try to wander around the cabin or do some simple exercises in your seat to improve your circulation.
How to get through airport security fast when flying to Buenos Aires?
- Security personnel first need to establish that you have a valid ID and matching travel documents before anything else. Have them within easy reach, ready for inspection.
- Time to strip down. Well kind of. Your belt, coat, keys and other small items, like your earphones, will need to go on a tray through the X-ray machine. Make the whole process faster by removing them as it gets closer to your turn.
- Your electronic gadgets like phones and laptops will also have to go through the machine for inspection. No need to worry though, you'll be back online in no time.
- Want to bring along your favourite perfume? As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you can keep it with you in your carry-on luggage.
- Lightweight sneakers are a sensible footwear choice as you're less likely to be required to remove them when going through security. Boots and other bulky shoes are often subjected to additional screening.
- Airlines will not allow any sharp objects in your carry-on baggage. If you need to bring these kinds of items, pack them in your checked baggage.
