How to save money on a flight to Greater London

Getting some of the best deals on flights to Greater London is all about timing and flexibility. Here are some key tips to help you save:

1. Compare flight options—use Expedia's search tool to compare airlines, routes, direct vs. non-direct flights, and flight times. You can also sort by price to find the most affordable options.
2. Set up price alerts—stay up to date on fare changes by using Expedia's Price Tracker. Receive alerts when fares drop for your selected route.
3. Bundle and save—book a flight and unlock a hotel deal on Expedia*, or explore our Greater London hotel and flight deals.
4. Travel during shoulder season-peak travel periods tend to push the flight fares a little higher than usual. Traveling outside of these busy periods can help you find more competitive prices while still being able to enjoy good weather and lesser crowds.
5. Be flexible with your travel dates-if your schedule allows it, try and search for a few different departure and return dates as this may help you find lower fares.
6. Consider economy fares-if you're traveling light and don't need extras like seat selection or additional baggage, opting for a basic economy fare can be a simple way to keep costs down. Just make sure to check what's included in the flight ticket before confirming your booking.
7. Think about luggage—it's important to check the airline's baggage policies to find the best value. That may be paying for an additional carry-on bag or booking a ticket with checked luggage included. Either way, double-check your baggage allowance before confirming your booking to avoid excess baggage fees at the airport.
8. Earn miles—you can earn airline miles when you book with Expedia. Make sure to select your frequent flyer program and enter your program number when confirming your booking to get more value from your trip.

Tips for short-haul flights to Greater London

For quick getaways, efficiency is key. Here is how to make your short-haul journey smoother:

• Pack light and skip checked bags—with budget airlines, it's often more economical to travel with just a carry-on. Maximize your space by using mini toiletries, wearing your heaviest clothes, and efficiently planning your outfits. This also allows you to bypass the wait at baggage claim upon arrival.
• Early check in—almost all airlines allow you to check in online at least 24 to 48 hours before your flight departs. This can save you time at the airport, and you might even secure a preferred seat without incurring extra fees.
• Bring your own entertainment—many short-haul flights may lack in-flight entertainment. Download TV shows, movies, music, or podcasts ahead of time, and consider bringing a book to keep yourself engaged. Remember to fully charge your devices before you board.
• Arrive early—Even for short flights, it's advisable to arrive at least 1.5–2 hours before departure, taking into account potential traffic and security lines.
• Bring your own snacks and water—pack snacks and a refillable water bottle to stay hydrated and save money while at the airport.

Tips for long-haul flights to Greater London

Flying long-haul sometimes requires extra planning to ensure a comfortable journey:

• Select your seat in advance—for longer flights, choosing your seat plays a crucial role in your comfort. Full-service airlines often allow free seat selection once online check-in begins, typically 24 to 48 hours prior to your flight. Some airlines may permit earlier seat selection, but this could involve an additional fee.
• Arrive early—aim to reach the airport at least 3 hours before departure for international flights to accommodate check-in, security, and immigration procedures.
• Relax at the airport—if you have spare time, explore the shops, enjoy a coffee at a café, or unwind at the gate or in a departure lounge if you have access.
• Adjust to the new time zone mid-flight—begin syncing your body clock by setting your watch and modifying your sleep schedule to align with your destination's time zone. Try to rest or stay awake during the flight according to the local time at your arrival location to help minimize jet lag.
• Dress comfortably—the journey will be lengthy, so opt for loose-fitting, comfortable clothing and layers, as cabin temperatures can fluctuate.
• Stay hydrated—bring a refillable water bottle and make sure to drink plenty of water to keep yourself hydrated, ensuring you feel your best upon arrival.
