Thanks for info. Since I have never flown Mesa let me anyway try it out. Wife and 4 yr old daughter would be in a day earlier in Boise and will be travelling a day after me back to LAX ( on United both legs ).

I had some schedule in office and couldnt join them and had to use this free voucher and I live in BUR ( 2 miles from airport). Since I am travelling single I dont mind the 6 hr total flight to BOI and the valuable experience I will gain with Mesa

BTW I just checked and found only the BUR - PHX and PHX - BUR are operated by MESA using CRJ900 . The PHX-BOI-PHX is operated by US airways Airbus A319.
