Instead of contracting companies in the UK (we fly a lot for the automotive industry) our customers might move south-eastwards to Romania, Czech, Slovakia, whatever instead. Which means more flying hours sold and better hotels and food for us crews for 1/3 of the price...
As all the staff in UK hotels is from Eastern Europe,they wil move back and nothing will change for you.
