Lastminute.com

Website:Lastminute.com can be used to book a trip anywhere in the world, but it specializes in European travel and is one of the continent's top three travel companies. Hotels are booked directly and can be filtered by budget, star rating, guest rating, board type, and other criteria. The flight section uses a metasearch engine to find the best deal across associated OTAs and airlines, and it includes the ability to add multiple destinations – a big plus in Europe, where short travel distances make city-hopping a popular option.

Lastminute.com also offers flight-and-hotel packages and all-inclusive vacation packages, which are frequently discounted for last-minute travelers. You can also book several Europe-specific travel services, such as Eurostar tickets (for those traveling between the United Kingdom and mainland Europe) and West End theater tickets. Another significant benefit for visitors to the UK is the company's Brexit Price Promise. Whatever happens to the value of the pound as a result of Brexit, you will not be charged any additional fees for existing bookings – even if only a deposit has been paid.
