Traffic Jam Gatwick Airport

Roadworks at Gatwick Airport, May 2019

The M23 is being upgraded to a Smart Motorway; so that by spring 2020 it will have four running lanes in each direction with a variable speed limit controlled by dynamic signage. Great news for future safety, congestion and journey times.

It is not such great news if you are heading to Gatwick Airport in May 2019 though, as a reduced speed limit of 50mph will be in place and a number of road closures will affect your journey.

We strongly advise that you add additional time to your planned journey and check this page for the most up to date travel advice before leaving.

We know there is nothing like the thought of a traffic jam when you're on the way to the airport to really sour that holiday mood. So, if you haven't already, why not book an airport hotel with us and spend the night before your flight safe in the knowledge that you can leave all those thoughts of traffic jams behind you? We offer a huge selection of airport hotels at over 25 UK airports, including 2-star, 3-star, 4-star and 5-star hotels, undercover hotels and hotels with family rooms. We're also the only company to personally test and review all the hotel rooms we have on offer, making sure you have everything you need to start your holiday off right.

We would absolutely recommend leaving extra time to get to the airport but why not think about booking an airport lounge just in case you didn't need those 6 hours for that 2 hour drive? There's nothing like planning for traffic and then sailing through in record time! They're really not as expensive as you might think and be smug in the knowlege that you'll have somewhere to avoid the hustle and bustle of departures and just relax before your flight.

Why not avoid the hassle of the motorway delays on the way to the airport completely and get a train to take you straight there? Did you know that Holiday Extras also offers airport by rail transfers?. Not only will you not have to worry about driving yourself to the airport, you'll also avoid those potential traffic jams and incidents on the road that that could affect your journey and result in rushing to the terminal, or even missing your flight.

    You should be able to find the answer to most questions online but we would recommend taking a look at the following advice from Which? in case you miss your flight due to traffic.

    Most travel insurance policies will cover you for a missed departure but it's worth checking the wording before you leave. And if you don't have any insurance then we'd strongly recommended thinking about getting some. Holiday Extras offers award winning, comprehensive and reliable travel insurance covering a wide variety of policy options so why not give us a call to make sure you're covered?
