Paris Airport - Charles de Gaulle Traffic Questions

From my own experience, a taxi ride from CDG airport to Opera should not be 30 euros... You can imagine a 10 minutes ride inside the city centre will cost you already 15 euros. Yes, 30 euros was possible, but it's in year 1997, when I first visited Paris, I took a taxi from CDG to Paris centre. The fare is 300 francs (equal to HK$330)
From CDG to Opera, the journey time is around 40 minutes. Also, after leaving the city centre, the fare will be increased automatically. Few years ago, I went to CDG airport on a taxi from Republique to CDG airport, it costs me 60 euros. Remembered that it's a story of few years ago !!! so you can imahine the cost now
Opera is the heart of the city centre. Traffic jams occurs everyday in the Paris city centre, it's a fact and cannot be solved. The situation is slight ly better in the summer. It's true that the way is clear after leaving the centre, but you have to wait in the taxi when it's still in the city.
Flight departed at 1445, then you have to arrive airport at 1245 and leaving hotel at 1200. It's the most congested time in that area... I recommend you going to Airport by another means. There is a "Roissybus" (bus) running between CDG airport and Opera. The stop is just next to Opera and the fare is only 8.90 euro. Will you consider this rather than a taxi ??

Hi,
The taxi fee is around H$ 300, it takes about half an hour from the airport to Opera.
It is hard to say whether there will be traffice jam on Monday because you did not say which day. Actually if you travel between end July and end August, the traffic should be ok because most Parisian will go to the country side for the vacation. So the traffic to the airport will not be heavy during this period.
