JetBlue TrueBlue - E190 on BOS/RSW route

Just booked BOS/RSW trip for Easter -- was suprised to find after purchasing
that seat map of E190 came up for Wed 6:20PM BOS departure --- has this a/c been used on this route before? Return flight is on A320.

190s have been running Northeast to Florida routes to help with the capacity loads we are facing.
