Not sure how you can make a judgement about why people are travelling based solely on the destination
LTNman? I suppose people from Eastern Europe don't have family emergencies or need to travel to/from the UK from work.
The problem is not the airports or the airlines but Government policy which has been confusing and unclear. The Government has that it is a personal decision as to what is essential travel and is up to individuals to decide. Look up Raab's statement from March 17 if you don't believe me.
