I need help with my eight day trip, (half in Paris, half in Toulouse):

1) Are there any low-cost flights between Paris and Toulouse, or is the TGV the best way to go?

2) I'm not fond of the overnight (sleepless) flight to Europe so I was wondering about the relative cost of a day flight to London (from Boston, NYC or Montreal--if significantly cheaper), overnight in London then the Chunnel to Paris.

3) What's involved in flying Boston or NYC to Paris, then returning by plane from Toulouse?

4) Cheap cellphone for a week or phone card?

Thanks, Howard Brattleboro, Vermont
