Hi ExpertFlyer Voice

I have two questions regarding inconsistencies in what I'm seeing in EF and what I see on airline seat maps.

First, on LA801 on April 6 (but I think it is every date as I had the same issue on LA800 on my outbound flight) not every seat shown as available on the EF seat map is available for me to actually select on Lan.com or via their call centre. As an example, seat 12L appears available in EF but I can't actually select it. The same for the middle row aisle seats in rows 15 to 17. My QF (gold) frequent flyer number is entered in expert flyer and is included in my reservation. One possible explanation I have is the perhaps Lan is only offering preferred seats to its own frequent flyers, even though this is a published benefit for OW sapphire. What do you think is going on here?

Second, LA801 is a codeshare with QF322. But EF shows different aircraft (Aircraft: 340 vs Aircraft: 343). I don't know much about the difference between these aircraft, maybe it's just a different configuration, but the issue is that the QF codeshare is showing row 26 to be an exit row, which, having taken this flight multiple times, I know is not true (row 25 is the only exit row). This may not be an EF issue though as I was allocated row 26 on my outbound when I asked for an exit row at AKL, and I was disappointed that it was not one, despite the agent's assurances at check-in.

Thanks very much in advance
