A quick, but specific, question:

3 of us travelling in J to TPA. Am looking at the seat map on MMB and checkmytrip.com and seatexpert.com, and they appear to show the seats in slightly different positions.

If I have 3D (which is the last aisle seat in the middle section), is this across the aisle from 3B or 4B? Or is between the 2 rows on the window side.

Am I best having 3ABD or 4AB and 3D, so that the B and D seats can talk together, so to speak.
