The absolute cheapest way from BDL to Amherst without driving is probably something like:
Taxi/Uber/Lyft from BDL to Windsor Locks train station ($16 taxi fare according to the list of fares found here, though note that it's from 2011; prices may have changed since then)
Amtrak Vermonter train from Windsor Locks to Northampton ($11 if purchased sufficiently far in advance)
Pioneer Valley Transit bus from Northampton train station to Amherst ($1.50)
Assuming all of the above fares are correct, the total cost would be $28.50 plus a $3β4 tip to the cab driver.
The tricky part of this is ensuring that you catch the Vermonter train. There is only one train per day, departing Windsor Locks at 2:22 PM each day. If your flight into BDL arrives any time after 1 PM or so, this itinerary may not be the most optimal.
