Getting to Paris??

Hello all,
I would like some advice on nonreving to Paris. With the wife's schedule, June or September would be best, with May or October as runner up. When am I most likely to find the best availability? I can easily get to any US east coast departure city.

Best month? Best departure city? Best airline?
Any tips or advice are GREATLY appreciated!!!

What are your carrier options? Zeds? ID90 tkts?
Do you have upgrade possibilities or coach only?
Just 2 pax?
May can be nasty grey wet.
Early June is probably good midweek (after Mem Day)
Best rule is go while school is in session here. I've had really good weather early Oct--college kids are finally gone and Eu is settled down.

We went a couple of years ago the first week in October. The weather was really good and it wasn't crowded. The best part, all the flights were wide open!

I vote for October also.The crowds are not as heavy then.I have been in July, September, and October.You should've seen the line for the Eiffel Tower in July.......

Guess I'll plan on October.

THANKS for the advice!!

AC flies to CDG from YYZ and YUL daily if that helps!
