Just a quickie - LHR - JFK, and then BOS - LHR.
I was going to get the Acela Express between New York and Boston, but I have since noticed that JetBlue are offering TWO SEATS for $129.00 - thats a bargain! Acela is $176.00 for two seats... not sure what to do. Is it a hassle getting to/from the city centres and JFK and BOS?
