Hi Gail!
Yes, actually I have flown out of Providence! It was a trip to Corpus Christi Texas and it was a sudden and necessary trip and that was the only place that I could get a quick flight out of. It is a nice airport...small, and I do keep my eyes on fares from there but BDL seems to beat out (or equal) PVD. I have never flown out of MHT (fares are usually much higher from there, and then multiply times the 4 of us) even though its 20 minutes from my house.
I think that PVD and BDL are just about the same distance from me.
