On December 11, 2008 we received a written quote via e-mail from this company for $55 to drive from Union NJ to JFK airport for our flight on December 17. On December 15, we called and made a reservation and the $55 amount was confirmed. On December 16 in the morning, the day before our flight, On Time called and said the quote was a "mistake" and they would have to us charge $85. We were leaving early the next morning. The timing of this is suspicious as it left us with less than 24 hours to arrange other transportation.
