Just an observation re Norwegian flights MAN-ALC. Because these flights operate in the evening, it is actually possible for Monday-Friday workers to travel over for the weekend without using up any of their holiday allowance. I haven't checked the MAN-AGP evening timings, but given days of operation include Friday and Sunday it is probably an option for this route too. I have already booked an Alicante weekender for GBP56.50 return. The cheapest seats will no doubt be snapped up quickly.
