I have flown that route pretty often, have never had any problems with carry in. But I did read the restrictions and complied with the 10kg total rule. Sad that this route will be ending, even with driving down from Quebec to SWF, this was a very affordable way for me to see family in EDI. The direct flight, cheap parking and low cost were a win. SWF is a small airport, security is always fast and I have never landed and been in my car within ten minutes in any other airport.
