Airlines always offer best deals if you book at least 2 months before your flight. However fares are made available 11 months before, so if you are sure on your plans book as early as possible.

Also avoid booking at weekends where prices can be potentially be higher than if you book during the week. These are marketing techniques and tricks used by the airlines.

Choose to travel out of the peak season. Summer holidays,Christmas, Easter and mid term breaks are always more expensive. As the demand is higher fares will be more expensive.

An added bonus is that when travelling on long haul routes at low season flights will be less busy thus ensuring that extra comfort would be greatly appreciated.

Departures on Monday to Thursday or Saturdays are often cheaper because you avoid the weekend get away. Also travelling early in the morning or late at night are often priced better than during the day.

Airlines are offering special fares for hand luggage only. If going on a short trip up to a week, it can easily be achieved by packing light. Some airlines will also allow you to check in your hand luggage at the airport check-in counter if the flight is full.This frees up space in the cabin plus making it easier for you not to carry so much luggage or you can buy things after security.

Attention! In recent years, low cost airlines are now limiting the size of the carry on baggage to a just a small personal item, like a backpack or small bag. Anything like a trolly bag on wheels, will be subject to additional charges depending on the airline, specially those by low cost airlines.(check before you travel or when you check-in online).

Airlines are very confusing when it comes to policies.They all offer different luggage allowance, size, pieces etc. If you travel light it might be a good ideal to compare airlines to work out what suits you best.

For a comparison see below: (Data correct as of Jun 2020)

✈️EasyJet (UK): has limitless weight on hand luggage provided it fits the size restriction. However it´s strictly limited to one item per person plus a personal item.

✈️British Airways:1 piece hand luggage allowance plus one personal item. The main trolley bag can weigh up to 23kg.

✈️Ryanair:has revised it's baggage policy and now only allows one small personal item on board for free.(this is a laptop, small backpack, handbag etc)
Trolley bag cases for hand luggage must be paid for.

✈️Wizzair:allows one cabin bag only at 10 KG max, but at reduced size. (like backpack or small bag). Trolley Cabin bag must be paid for in advance.

✈️Norwegian: allows one main cabin bag (trolley bag), max 10Kg, plus one personal item

✈️Vueling:also allows only one main cabin bag at 10kg (trolley bag) plus one small personal item

✈️Lufthansa Group (Swiss, Brussels Airlines, LoT, Austrian Airlines:These airlines allow one hand luggage item at 8kg (trolley bag) plus one personal item

Reserving a seat online is common on many airlines. However, most are starting to chose for a seat selection at the online checkin. (Ryanair, Easyjet,Wizzair, Iberia Express, etc..) If you don't mind where you are seating get the free random seat allocation and sometimes you might be lucky getting what you want.

Tip! You can always change your seat by asking at the gate the availability in most airlines for free. (except for low cost airlines like Ryanair, Wizzair, Vueling, etc)

Travelling to main airports can be more expensive by the location but when a city has two or more airports it's worth checking the prices as there is a big difference in airport tax, which ultimately passengers pay for in their tickets.

For example London, Frankfurt , Paris, Tokio, Seoul, Buenos Aires, New York, Los Angeles etc have more then one airport.

Booking a combination of flights departing and arriving to different airports are a tax headache for the airlines. Return tickets are calculated with all taxes being added from the same airports but when you combine different destinations, the mathematical equation gets more complicated by fares, taxes and fuel surcharges.

Playing around a little and combining different alternative airports and dates can make a huge difference to your final travel costs. This might involve travelling to a further airport from you, or buying an extra one way ticket to your first destination where your mulcti-sector flights itinierary will start.(overall the extra time still saves money, that's the goal).

For example a direct flight from London to Kuala Lumpur return can cost £550. When combining different airports and adding transit stops, airlines will combine lower taxes and often making mistakes on the fare calculation, therefore creating what we know as the "Error-Fares"

We found that departing from Lyon (France), then transiting in London and flying home from Singapore to London, was cheaper. Total price was £210 for a return flight. If you add the additional flight to Lyon this will only cost an extra £45 making a grand total of £255. Saving an incredible £245!!

When buying an itinerary with an airline containing two or more flights (transits) it's very important not to miss any of them except from the last flight. When this happens the system automatically cancels the rest of the sectors and the flights can be overbooked more easily. To be able to use the ticket the airline has to reissue the ticket for it to be "in sequence " and this might cost the passenger more money, if not, a whole new ticket.

For example: Buying a Multi-sector flight Brussels-Madrid-Tokio-Madrid-Frankfurt ; if we miss the first sector and decide we will commence our trip from Madrid. When you will get to the airport they will not find your reservation and the ticket will be invalid because you are trying to make this sector your first one, but in fact it's your second one as per the ticket.
Automatically your ticket will be cancelled and to reissue will cause a delay and a problem for you financially.

Airlines, online travel agencies and tourism companies often use promotional discount codes to tempt travellers to book. Keep an eye for them by subscribing to the website or following deal pages. You can often save a 5-20% over the original price.

Tip! Other useful tools include getting cash back on your purchases online.
Pages like Quidco or Topcashback give you money after you have flown or stayed at hotels.

Low cost airlines make you pay for food and drink. So why not take your own packed sandwich with you and refill an empty bottle with water after security?

Though the key is to save money, often you feel like you want to treat yourself to an upgrade. Paying online for an upgrade before you fly is worth checking, to see if they have unsold Business Class seats. You might find good deals for the one way trip.
Alternatively ask at the airport, but note that airport fees for upgrades are always more expensive than buying a return trip in Business Class online first.

Additionally from these tips related when buying tickets to travel by air you can also make a note of the following tips to save you money (and often time) when you arrive:

attach_money Exchange money prior to arriving at the airport: Airports takeaway huge commission rates when compared to high street branches. Often there are now coupons and vouchers and can find better deals by submitting online orders.

thumb_up Travel reviews and opinions:As like with this website where you can find useful information about the destinations you are planning to visit, it's very handy to know others people's opinions and experiences so you can have a basic idea of what to expect.
Many tourists travel unaware, and by surprise or by accident they find themselves scammed, overcharged or tricked into believing a locals advice on arrival. Checking reviews of your destinations, hotel reviews etc will make sure travel more relaxed and prepared.

update Adapt to the local hour: When travelling long-haul it's very typical to suffer from jet-lag the first few days. It’s a natural adaptation of the body to a drastic change in hours, especially when travelling eastwards as the time goes forward.
When arriving make the most effort to stay awake and busy during the day till the late evening. So your body can adapt quicker to the time change. Drink plenty of water and refrain from extreme sports or alcohol during a few days as the body is still adapting.

sentiment_satisfied_alt Well being on board: Travelling many hours on a plane can be very tiring, even you are not doing much in fact. Due to the small space (Economy Class), your body accumulates tension, blood pressure changes and it's harder to maintain concentration when writing, reading, watching screens etc.
The cabin air is pressurised and this adds a feeling of being tired when travelling.
It's advised to drink plenty of liquids (never alcohol) to mitigate this feeling.
Additionally it's recommended to get out of your seat every two hours to stretch your legs and muscles. Using balms, hand creams, and other hydrating products will help you get a rested look as well.

Last but not least, it's recommended to do small exercises from your seat, in order to maintain a good blood circulation and avoid cramps and pains. Specifically, for older people.
You will find these exercise techniques in the airline magazines supplied at your seat pocket or by asking a member of the cabin crew.
