Mr. Hat,
Have a look at the 190 fleet numbers compared to the 700. Currently there are 16 190's in service with 2 more to come this year compared to 18 700's. All bar 2 700's are leased and all the 190's owned. The oldest 700 VBA is approaching 10 years old and the rest are not far behind it. All new 737's coming are 800's so it would appear the 700's are on the way put behind the 170's.
Yep some important dates are fast appraoching and still nothing about the ATR package and where the first east coast base will be. So far I've heard TSV, BNE, SYD and CBR all mentioned as the first but depending on who you talk to they have reasons why any of the above would be the first or why they wouldn't.
