Important Considerations To Think About Before Reaching The Airport

Having a flight to catch? Are you fully prepared for the departure? Well, you are not fully prepared for takeoff until you learn about some essential things that most people don't care about. Things like the 3-1-1 rule, airport arrival times, and allowances for exceeding baggage limits are normally not the first things most people notice, but they actually matter, especially when buying low fare air tickets with reputable carriers like British Airways. This page covers some of the most essential things to consider before you arrive at the airport. 

Can I get to the airport 45 minutes before my flight?

Yes, you can, but only at your own risk, because 30-45 minutes before the flight's departure is crucial, leaving no time to pass through check-in, check bags & security screenings, which can take time, and the passenger might be late for boarding. Many international carriers recommend arriving at the airport at least 1-2 hours before domestic departures and 3-4 hours before international departures.

What is the 311 rule on British Airways?

British Airways has certain restrictions and requirements for keeping any kind of liquids, gels, or aerosols in hand or checked luggage during travel, depending on the route. The airline calls it the 3-1-1 rule, which, in simpler terms, guides passengers on best practices for carrying such items when traveling with British Airways across the UK, the EU, and other regions. Here are some main highlights of the British Airways 3-1-1 rule, for your reference:

  • At some London Airports, passengers can carry their liquid items in containers measuring up to 2 L.
  • At other UK airports, passengers must keep all their liquids in a separate container, and the amount must not exceed 3.4 oz (100ml). 
  • All liquids must be kept in a single transparent resealable bag. 
  • The size of the transparent bag must be up to 20 x 20 cm (8 x 8 inches), and have a capacity of no more than 1 liter.  
  • In case of carrying alcohol, the 3-1-1 rule still applies for carrying a cabin bag; however, there are some additional requirements to be met:
    • There's no limit on the number of alcoholic beverages as long as the concentration is below 24%.
    • For between 24% and 70%, up to five liters can be carried when bought from a duty-free shop.
    • When the alcohol concentration exceeds 70%, it is not permitted in the cabin or in checked baggage. 

Is the 311 rule per bag or per person?

No, the 3-1-1 rule is applicable on a per-person basis, not per bag. According to the 3-1-1 rule, even if it's the cheapest flight booking, each individual may carry permitted liquids, gels, or aerosols in a resealable bag weighing 3.4 oz (100ml) or less. Here are some key features of the 3-1-1 liquids guidelines provided by British Airways that you must not ignore before packing your bags if you don't want to fall into unexpected inconveniences, which include:

  • Liquids should be carried in one bag in your hand luggage; if the size or weight exceeds the limits, they can be placed in a checked bag.
  • For screening purposes, all liquids may need to be taken out of bags at the airport, whether carry-on or checked. 
  • For international travel outside the UK & European Union, the 3-1-1 rule may vary by airline or by country's laws for safety and security, so do check them before flying.
  • Countries like Kenya can impose strict bans on Plastic Bags, so it is recommended to use a thick, transparent, reusable polyurethane bag within size restrictions. 

What happens if you go over 23kg?

On the day of departure, when packing your bags and preparing for the trip, it is common to exceed the 23 kg checked baggage limit. Although airlines are usually strict about their baggage allowances, especially for their cheapest flight, that doesn't mean your baggage must be exactly 23.00 kg; you can expect a few grams of flexibility. However, in most cases, if you exceed 23 kg, you are considered overweight, and conditions apply per the airline's overweight/oversized baggage policy. You will most likely be charged an excess baggage fee if your baggage exceeds the limit by 0.4 kg. Here are some tips to consider if your bag exceeds the 23 kg limit. 

  • You should purchase an extra allowance through the airline's online portal to avoid extra service fees.
  • At the airport, you can transfer some things to your carry-on or personal items to help reduce weight. 
  • You should double-check the weight of your checked bag before leaving home and distribute the weight evenly across all your bags. 
  • Ensure you purchase lightweight suitcases, trolleys, duffels, or bags.

Hopefully, through this guide, you have found valuable information that must be taken care of when flying with esteemed airlines like British Airways across the UK, the EU, and beyond.
