How to go from Paris to London cheaper by train?

I have ever been to Paris from london many times.
Flight, Coach (euroline) and Train (EuroStar) are good actually. It depends on what r u going to do in your trip.

If you select take a flight, the cheapest airline company should be ryanair & easyJet.

www.easyjet.com
however you have to consider the transportation fee from london centre to london and paris airport to paris centre. You would better count this cost into flight tickets. I bought 10 pounds ticket for single. but I spent a lot of time and money to airport.

Eurostar is the most convenient and faster from london to paris. I am sure if your budget is 125, it s quite easy to get it, and u might be able to get cheaper as well. My friend got a ticket recently which is 59 pounds return. cause there have a promotion in eurostar web.
* To purchase the ticket at least a month ago

Coach is a reasonable transport from london to paris. I have ever bought a ticket 12 pounds single ticket. however, it is the same that u would better purhcase it a month ago. taking coahc has to take more than 7 or 8 hours.

I have no experience in taking a ferry. I have checked about the return tickets in Feb, there are 37 pounds available as well. I would suggest to take this instead of flight.

You may try : www.lastminutes.com for air tickets.

You can also try hire-a-car journey from Paris and return your car in London. Bring along with your International driving license ( + credit card). You may head to Calias / Dover then with you car on board the train through the English Channel , start the trip in England by car.

If you come on 18th Feb 2008, this is the half-term ( school holidays 18-2-08 -- 23-2-08) of England, the air ticket will be more expensive ( or fully booked).

Good luck.

你可以嘗試搵廉價航空公司,有d飛機票可以平到0.01歐羅一張(當然稅比較高),但通常20歐左右已經有單程票
這個網站入面有不同的廉航網頁,你可以search下

不過要訂票就要快d,否則可能會無哂d平機票

Yes, Easyjet is cheaper. You can also take the National Express. But the cheapest of all is to take the ferry!
