"It appears that QF Link may be in for some real competition. "
I can't really see the link having any competion on this route despite aerotropics attempt to service it with the E-jet.
Think about what qantas can offer:
1. the 400 for starters will reduce the flight time to 1hour 20 mins making it only approximately 20 mins slower than the jet.
2. The back up of many additional aircraft available in the event of breakdowns etc.
3. the frequent flyer points, lounges and most of all the connections to main line qantas flights.
Could go on here but i won't.
Im not too sure about what tropos are offering and it is great to see them having a go...... but from where i am sitting it is hard to see them really competing with the rat on this one.
