Several.potential.consequences.of.this.sampling.methodology.should.be.kept.in mind.when.reviewing data.collected.from.passenger.surveys..Only those.passengers.aboard.business.aircraft.whose.pilots.or staff members.were willing to.disseminate.the.survey were.contacted..Pilots who refused.to.distribute.the packets.or.selectively distributed.them.(perhaps excluding.certain.passengers like.top.management) may have.had.an.impact.on the sample.of.passengers who received.the.survey..Additionally,.since.the.survey is.self-completed,.the.sample.of.passenger interviews.is.based.upon.only those.passengers who.read, completed,.and.returned.the.survey..One.might.expect.to.reach a.slightly.more.representative.sample had a.random.sample.of.all.business.aircraft.passengers.been.accessible and.used.to.conduct.online.or telephone interviews. Weighting.of.Data The.pilot.data for.the.number.of.aircraft.per.company.and size of.aircraft.were weighted where.necessary to.bring.them.into line with.their.actual.proportions.in.the.business.aircraft.population..The.actual proportions were.derived.from.data.available by.JetNet.(see.below)..The passenger.data were not.weighted.
