Delta/Virgin Australia Codeshare Booking
Looking at booking TPA-ATL-LAX-SYD and MEL-LAX-ATL-TPA. Started searching premium economy options via Google Flights and found some preferred flights and was routed to Virgin Australia site for the booking. LAX-SYD and MEL-LAX are both on VA and I am able to select premium economy seats on the VA site. Flights from Tampa to/from LAX are all on Delta. Google flights indicated that these flights are in premium economy but Delta does not offer premium economy on these domestic routes. I cannot book Delta seat assignments through VA site so will have to go through Delta to do this once tickets are purchased. Does anyone have experience with a similar codeshare booking? Will I end up with Comfort+ seats on Delta or economy? Is there any chance I end up with Basic Economy (which can't be upgraded)? TIA
