Our Review of London Heathrow Airport (LHR)

At Plan Your Trips, we have analyzed hundreds of airports around the world, allowing us to better understand what modern passengers truly expect when travelling through an airport. Based on this experience, we created this guide with a clear objective: helping travellers move through London Heathrow Airport (LHR) in the fastest, simplest, and most reliable way possible.

Our approach focuses on practical information, realistic travel expectations, terminal navigation, transport connections, passenger services, and the overall airport experience. We understand that many passengers arrive at Heathrow under time pressure, often dealing with connections, long-haul flights, jet lag, or busy travel schedules. For that reason, this guide prioritizes clarity, efficiency, and real-world usability.

In addition to providing operational information, we also closely analyze passenger reviews and public feedback from major travel platforms and airport communities. Heathrow Airport is consistently recognized as one of the world’s leading international hubs thanks to its huge global connectivity, modern terminal infrastructure, extensive airline network, excellent shopping and dining offer, and fast transport links to Central London.

Passengers frequently praise Heathrow for its efficient rail connections such as the Heathrow Express and Elizabeth Line, the modern design of Terminal 5 and Terminal 2, the large selection of premium lounges, and the wide variety of restaurants, luxury shops, and passenger services available throughout the airport. Heathrow is also highly valued by international travellers for its role as one of Europe’s best-connected long-haul airports.

However, passenger reviews also reveal some recurring weaknesses, particularly during peak travel periods. The airport can feel heavily congested during busy mornings, weekends, summer holidays, and major international travel periods. Reviews commonly mention long walking distances in some terminals, queues at immigration and security, crowded gate areas, baggage delays, expensive parking fees, and occasional operational disruptions linked to Heathrow’s extremely high passenger volumes.

As one of the busiest international airports in the world, Heathrow operates very close to maximum capacity, which means that even small disruptions can occasionally create delays across terminals and transport systems. Despite this, the airport generally maintains strong passenger satisfaction scores compared to other large European hub airports. Heathrow has also invested heavily in terminal modernization, digital information systems, baggage handling improvements, and future infrastructure upgrades aimed at reducing congestion and improving passenger flow.

Our Final Score: 8.7 / 10

London Heathrow Airport remains one of the best large hub airports in Europe thanks to its unmatched international connectivity, modern terminals, excellent rail access to Central London, premium facilities, and extensive airline network. While overcrowding and queues can occasionally affect the passenger experience during peak periods, Heathrow still delivers a highly efficient and globally competitive airport experience considering the enormous number of travellers it handles every year.

How we calculate On Time Performance

On various pages of our website, you will encounter a metric widely utilized in aviation and other forms of transportation known as OTP (On Time Performance). We believe that providing this metric assists passengers in planning their trips and exploring alternatives before purchasing their flight tickets.

We calculate the On Time Performance for all flights and airlines, when we have enough data to do so. In certain instances, it may not be feasible to accurately compute the On-Time Performance for a specific flight or airline due to inadequate or non-representative data, which could result in misleading conclusions.

Our calculation of On Time Performance and delay information solely relies on arrival times. This approach is chosen over calculating departure delays, as we consider arrival punctuality to be of primary concern to passengers.

The On Time Performance displayed on our website is calculated as follows:

On Time: Flights that arrive within 15 minutes of their scheduled arrival time, or earlier. In the absence of data for a specific flight, we assume the flight arrives on time, to avoid penalizing airlines for data unavailability.
Moderate Delay: Flights that arrive with a delay of 15 to 30 minutes.
Significant Delay: Flights that arrive with a delay of 30 to 60 minutes.
Major Delay: Flights that arrive with a delay exceeding 60 minutes.
Average Delay: The average delay is calculated by considering flights that arrive early as having a delay of 0 minutes. Early arrivals do not contribute to reducing the average delay calculation
