If you take just a 90-seat passenger airline aircraft...if the crew held out a tip jar, and assuming 2 FAs and 2 pilots. If every passenger just tipped $4 every flight, $1 per crew member, each crewmember would make $54,000 in addition to their current salary. Lets take a 1hr30min flight for example, and say you fly 900 hours per year (airline pilots are limited to 1000 hours per year)...

Makes for an avg. of 600 flights per year.

Each crew member would make $54,000 more per year (before tax) in addition to their current salary. i.e take $23,000 starting for 1st yr. FO that would be $77,000. This theory disappoints me. But so true and so simple. It is only $4 per passenger. Lets put the word 'profession' back into the professional pilot career. PASS THE WORD ON.

They can do the same for fuel prices. Just raise it an additional $1 or $2 in addition for jet fuel, making it $6 more per 1.5 hour flight. Just a few bucks will help with fuel prices, for now.

What is $6 per person on a $500 ticket? Its negligible. But goes a long long way.
