Here's a question to put forward;
/rant start.
If I'm a frequent flyer (WP) with Qantas and buy a ticket with a Qantas flight number that Qantas choose to operate through a codeshare arrangement with a partner airline, why can't I still have access to a Lounge before my flight?
Is lounge access a 'benefit' that will be further eroded by an increase in QF codeshare flights?
Example:
Originally booked QF ADL-SYD-HKG-BLR return.
Due to work commitments had to change return flight to BOM-SIN-PER-ADL, sold as QF3950-QF072-QF584.
Additional cost to change; $291.00
QF3950 = codeshare = no lounge access.
No lounge access = unhappy customer = no more codeshare flights.
No more codeshare flights = lost revenue for Qantas and codeshare partner, and win for either *A or Virgin.
/rant over.
