Regarding QF international ops out of Perth, agree they should have an A332 doing Perth Dubai Perth, and should have negotiated that with Emirates as part of the deal so not too much capacity!
Also assuming a 738 could fly Perth to Singapore?,
then why didnt Qantas replace the A333 to Singapore with a 738, and at least maintain a presence internationally out of Perth, and allow those passenegers who want to fly Qantas the opportunity to do so?
