Since I've now paid to reserve our seats I can't stop changing them. In May hubby and I are travelling LHR-MIA-CUN and the return flight is CUN-LGW. Outbound day flight I've changed seats 3 times...have now got 64A/B and return night flight changed 4 times...now have 5J/K. As this is a surprise special birthday present for him I want to get the seats right as this will be my first time in CW but his second. Have I finally made the right seat selection?
