I will be parking at Boston Logan for two weeks and looking options.

The airport economy parking is $20/day. I see mention of Park Shuttle & Fly, and PreFlight offsite lots for ~$100 /week. I'll be coming from the west on I-90. Any informed opinions?

I would consider Logan Express in Framingham. The lots you mention are probably fine - we used Park Shuttle and Fly some years ago and I see their lots when in East Boston. Finding the lots with a GPS or good directions should be fine - but you need to find your way past the airport into East Boston (same part of Boston where airport is located).

Logan Express is one of 4 locations run by MassPort. Parking is $7/day - and there is a bus from lot to terminal, usually every 30 minutes, but check schedule. Bus costs $20 or so RT. Perfect location if you are heading in on MassPike and then they deal with any traffic hassles closer to Boston. We have used Peabody and Woburn locations many times (though never Framingham).

I have used the Woburn location when I've had an early flight but usually use the Concord Coach bus from NH.

I live in western Mass. Everyone I know uses Logan Express. Do far I've always had someone to drive me, but if and when I run out of friends/relatives to take me to the airport I will definitely use it.

Thanks. From Framingham the weekend schedule is hourly both directions. Coming from upstate NY so we'd have to get the timing right or have to wait till the next hour (same going both ways).

At this point I'm tempted to use one of the private offsite lots - another one that pops up is Thrifty. I've had good success with these type of lots at many airports and don't have an issue navigating.

Another option - stay overnight at one of the hotels near Logan that include parking in room rate. There are several I found for about $300 - depending on time of flight, might make sense. (boston.parksleepfly - but I am sure there are other options other than these - I have heard that sometimes people call local hotel which normally offers free parking and ask about parking for longer after stay)

Consider renting a car at your home destination, dropping it at Logan and doing same when you return. Where we live, the cost of 2 one way, one day rentals is less than parking for two weeks.

We stayed at a Ramada which was 10 minutes from the airport and had a shuttle 24-7. They kept the car for 10 days included in the room rate. There are several others both north and south of the city.

I've used Thrifty many times, no problems. Easy to get to, just past the airport. They park your car for you and shuttle you over to your gate. The drive from their lot to the airport is about 15-20 minutes. I've also used PreFlight, which is also good, but last time I was there, a bridge was closed, so their shuttle ride was about 40 minutes. All of these lots offer online cupons.
