I personally would rather travel the day before New Year's Eve/New Years Day so that you are in the destination for the celebration. (Hence busy days yesterday/today)
Also to add, G-GDFD B737-800 to join the fleet imminently. G-GDFC B737-300 to follow shortly after.
G-LSAL and G-LSAM both B757-200 arriving in the coming months. It may be quiet now, but come May....
