We have just booked tickets to Lapland from Manchester (UK) with Thomson.
All the information that I had pointed to the aircraft being a 737-800.
I have just chosen the seats on-line. It is offering a 3+3 configuration with 37 seat rows.
Other operators that use the 737-800 have only 32-33 seat rows.
www.seatguru.com shows extra leg room seats on a Thomsonfly 737-800 as being at the front - but for us, the extra leg room seats were in rows 11 or 25.
This leads be to believe that it will be a 757 - does anyone have any thoughts ?
