Hello -- I have never had to change planes at a European airport and need some info and advice. In my few trips to Europe I have always managed to fly nonstop (and am willing to drive several hours to my departure airport for the convenience of doing so). But I am flying into Vienna and out of Venice this May/June, and am faced with paying a lot more money for a nonstop, just because there are so few into Vienna. I should have grabbed the fare of about $1050 I saw out of Toronto at the beginning of the month, but wanted to wait to watch for a while and the price has been going up up up daily and is now more than $1250 (there are 3 of us so that's a jump of $600). The only direct flights from NYC area airports start at about $1400.
Although I'd still rather fly nonstop, I am now considering a couple of options. Pricewise on major airlines, it looks like Air France might be my best bet, with fares less than $1000 (actual savings close to $900 total). But it would mean transferring at CDG. I think it is one of the worst airports for transferring, just because it is so big and so busy...am I right about this? Is it a lot worse than Amsterdam or Frankfurt? Which are the better airports for transferring and which are the ones to avoid if at all possible?
How much time should I allocate for a transfer to ensure I don't miss my connecting flight? There are several options with a 2 hour layover, which seems like it might be cutting it close? My other options are 4-5+ hour layovers. What is the best option for CDG?
Finally, could someone please walk me through what happens when transferring planes in an international airport en route from one country to another. Do we merely walk to our next gate, or do we need to go through customs or other such points? I am a complete novice here, so step by step info would be really helpful.
Finally, what are your opinions on the pros and cons or arriving at your destination city at 8:30 a.m. versus at 2:30 p.m.?
Thanks!
