I would be curious to see some numbers in terms of route flexibility for EZY and LS. The latter seem to have been very good with this so far, successfully rerouting lots of the traffic from the quarantined markets to the free-travel ones (e.g. by adding quite a lot of extra flights to Cyprus and Turkey in place of the cancelled ones to Spain). "Meeting the demand" is too broad a term. Sometimes it needs this sort of significant adjustment of the offering instead of flying empty into destinations with almost inexistent demand for the sake of maintaining presence there.
