Terminal change in Philadelphia

Looking at a return from SXM to SEA through Philadelphia. Says there is a terminal change. Is that a big thing to do or is it just a long walk to the connection?

How long is the layover?

We went from C(or D?) to A..it is doable in an hour and a half. There are moving walkways.

We just went thru PHL from SXM in June. The only terminal you have too worry about taking a shuttle(bus) to is Terminal F and I'm sure if you're going to SEA you won't be.

Thanks. We do have GE and are flying FC. Layover is 1:40. Just looking at options. Might do the SXM-CLT-SEA route with a 1:25 layover instead if the prices are good.

After many trips to de ilons, and reports of fellow travelers, my advice is to AVOID making a transfer at PHL if at all possible!!! PHL is OK for beginning and ending a trip but almost every transfer has been a disaster. <img src="http://www.traveltalkonline.com/forums/images/graemlins/smashpc.gif" alt="" />

In April we transferred from terminal a to f and f to a. Both ways was an 1:40 mins with a shuttle bus and had plenty of time. A year ago it was tight both ways.
