Travelling by air essentials

The earlier you buy your plane tickets, the higher the chances of scoring the best airfare. Nothing new here. Following the accounts of the airlines on social media may help here as very often they run flash sales or announce deals there. Also, the members of airlines’ frequent flier programs often are the first to get access to the best deals, so you may want to join one or more of such programs, especially if you are on the go.
Low-cost airlines are a great budget-friendly way to travel, but you should remember that many of them use secondary airports either farther from the centre or simply less convenient. Sometimes it takes much longer to get to/from these airports than from the ones used by the scheduled flights and pricier as there may be no public transport except taxi. And taxi will most probably offer inflated rates – well, they know you will agree to go anyway as there are no other options. So do check these points before you book your low-cost airline ticket. If you plan to use connecting flights, always check whether they are operated to/from the same airport or terminal.
Many budget air-carriers do not include any checked-in luggage or inflight meals in your air ticket price. It is wise to check what is included and what is not in advance. It is always cheaper to buy any extras you may need before the flight as at the airport or on board you will be offered higher prices. This especially refers to the luggage – quite often it is twice as expensive if bought at the airport at check-in.
Online check-in is now a must with many low-cost airlines. If failing to check-in online or at a self-check-in kiosk, you will have to pay extra for checking-in at the counter.
If you are travelling in a group and want to keep your party together, paying for the ‘choosing the seats’ option is a good idea. Otherwise the system will assign you seats scattered around the cabin. Yes, sounds unfair but it is what you will most probably get.
Blankets are usually not distributed on short haul flights but air-conditioning may be excessive. So pack layers to feel comfortable. Bring on board a lip balm, eye and nose drops, moisturizing hand cream – all these will help your skin remain hydrated during the flight in a very dry cabin air. Taking off your shoes and putting on socks instead will make you more comfortable, especially if you are prone to swelling. And do not forget to drink water during the flight – it is either sold or available free of charge.
Do not throw away your boarding pass after boarding – it may be required to show it at the immigration at your destination if you fly internationally and sometimes even after domestic flights at luggage claim.
