Air booking information released by Amadeus is showing a huge surge in UK arrivals on 26 July, the day before the Olympic Games begin.
The data, carried out in conjunction with market research company Forward Data, shows a 143% spike in inbound air arrivals compared to the same time last year.
For the four days before the event begins inbound air booking arrivals are up 31%.
Inbound visitors into European cities connected with London by high-speed rail are also experiencing inbound increases in arrivals by air - 49% in Brussels, 28% in Amsterdam and 5% in Paris.
Amadeus UK boss Diane Bouzebiba says there is a general trend of travellers using other European hubs and then accessing the UK by rail with operators looking to form partnerships to provide a seamless journey for travellers.
And, despite all reports to the contrary, Londoners are not deserting the capital during the Games with scheduled departures from the capital's airports showing they are 11% more likely to stay than they did during the same period in 2011.

"From a sales perspective there is the potential to customise products or specific services to certain segments and the technology enables travel agents to do that.
"There are also niche players that can handle the domestic traveller who seems to want to stay in the UK during the period.
"From an operations side we're going to have a lot more travellers coming through London and this allows airlines to analyse the data to see how it might present an opportunity for their business."
Bookings from US tourists have seen the biggest surge at 82% surge and represent 17% of scheduled arrivals followed by German travellers at 11% of arrivals.
Curiously, Estonia is recording the largest increase in visitors to London with a fourteen-fold increase.
The study also shows increased volumes from long-haul destinations including Jamaica and Brazil.
Amadeus partnered with Forward Data in 2010 to provide business intelligence to customers of the GDS.
The data is based on bookings by online and offline travel agents on any global distribution system up until 22 February.
