thanks to all the replies!
yes it is a difficult choice...
the airline with the -400 is a much bigger airline, more routes, with all the modern facitlities and the ones with the 73's is much smaller
on the one hand i know that jet pic is gold
on the other hand i do want to see the world
also, im single, no kids, no mrs...
so some guys say to go for the -400 position
i've got a few more weeks to think it over
thanks again
