Simplistically, half the rows empty, 3/6, and one third of the rest, 2/6, gives a pax load of about 30-35%, so tickets three times the price.
(As I said simplistic, as the hold fright will contribute).
Long distance tourist traffic will collapse, but LC carriers such as EasyJet might be able to cope at reduced volumes - an extra £150 on a Summer holiday won’t put everyone off, and the hotel prices will be lower as they will be desperate fir costumers - and it will still be cheaper than hotel costs in the UK fir stsycstions.
My question was more on the lines of do the operating seat costs per mile scale directly across all types?
e.g. If it is cheaper to fly a 90% full 777 than a 70% full A-380, will it still be cheaper to fly a 30% full 777 than a 30% full A-380?
