It's very hard with airlines like Jet2 and Monarch to draw the line between scheduled and charter.
Its quite easy really. With Monarch all ZB flights are scheduled and MON flights are charter. With Jet2 all flights are scheduled except those you cannot book flight only.
and I expect to see charter pax up this summer
I hope you are right but if the charter pax number is down for June, it doesn't look likely.
However, there may be a boost to charter pax numbers as, according to this mornings papers, Tour Operators are heavily discounting hundreds of thousands of unsold holidays for July and August some by as much as 60%. If these reports are accurate, the package holiday business must be in a desperate mode.
