What Is The Ideal Period To Reserve Flight Tickets To London?

According to data gathered throughout several years, the most favorable time to fly to London across the Atlantic is the beginning of a new year, January and February. This is the moment when prices reach their lowest point, while tourists are not interested in traveling due to the end of winter holidays and the upcoming spring vacation. The second period of cheap flights occurs from late October through early November after the foliage season and children's half-term school holidays have ended.

The worst periods to fly to London and spend additional funds are spring vacations (March-April), summer vacations (June-August), Christmas, and the New Year celebrations. During these periods, ticket prices can rise by 50-90% in relation to standard rates.

Comparing the London Airlines, Policy, and Option

London Heathrow Airport is regarded as one of the world's busiest international airports, which serves over 79 million passengers per year and is connected to various destinations located all around the world through different continents. No matter whether you are going long haul or short haul, airlines flying to London provide a wide variety of options, varying in prices, cabin offers, and baggage policy. Here is a brief overview of the major airlines that have flights to London and their baggage allowances.

British Airways

  • One cabin bag and one personal item are generally permitted on British Airways fares, including hand-baggage-only tickets, while checked baggage depends on the fare purchased.
  • The UK national airline with the largest fleet, the largest network of flights and destinations in London, among other airlines, covering Europe, America, Asia, Africa, and the Middle East.

Virgin Atlantic

  • One cabin bag is included on Virgin Atlantic fares, including Economy Light. Checked baggage allowances vary depending on the fare type selected.
  • London-based carrier that provides a good passenger experience and excellent flight quality at competitive rates, especially for transatlantic services.

American Airlines

  • Carry-on baggage and a personal item are generally included on transatlantic American Airlines fares, including most Basic Economy tickets, while checked baggage allowances vary by fare type.
  • Flies via the deep codeshare with British Airways under the oneworld alliance, giving comprehensive connectivity into Heathrow from all over the world.

  • Delta passengers generally receive one carry-on bag and one personal item on transatlantic flights, although baggage allowances may vary by fare type and route.
  • Closely partners with Virgin Atlantic on its transatlantic network, providing comprehensive connectivity into London, a good onboard product, and punctual flight operations.

Norse Atlantic Airways

Hidden Fees Watch Out For When Booking US-London Flights

Transatlantic flights have always been known for their enticingly low base fares, which end up being significantly higher when all is said and done due to a whole host of additional fees that come with purchasing such a ticket. Low-cost carriers such as Norse Atlantic Airways and Level Airlines adopt the so-called bare-bones fare strategy, whereby almost everything from checked luggage to priority boarding comes at an additional charge. Even more expensive legacy airlines are known to charge as much as $75-$120 in a fee for gate-checking a roller bag, as it does not qualify as a personal item.

What should you verify before confirming your booking?

  • Overhead bin access vs access to storage spaces below seats
  • UK Air Passenger Duty (APD), an air travel tax that is often already included in most transatlantic fares but is still important to double-check
  • Fees for seat selection – especially in economy class when flying more than 7-9 hours
  • Terms for changing and canceling flights, as they will apply when buying a non-refundable fare in advance
  • Whether or not your credit card includes travel insurance
