Compare travel to Paris

Air France

Frequency 12 flights a day from Heathrow to Paris Charles de Gaulle. Air France also flies from London City to Paris CDG (six times daily) and Orly (once).
Leg room The middle seat is always kept empty.
Price A return business-class ticket is £239.
Convenience Air France offers internet check-in and "automatic check-in" at the airport. It might be the cheapest business-class fare of the three, but what you save in money you make up for in the time lost simply getting to, and then through, Heathrow.
Food and drink "Complimentary catering".
Extras Not much in the way of corporate treats—Air France's short-haul business class is very different to its long-haul offering. Buy this class of ticket on the Paris route and you'll get "access to the Frequent Flyer Programme" and that's about it.
Carbon cost 144kg per person at a cost of £1.65.
