Yeah, effectively sounds like they're adding a drink to Preferred seats and presumably increasing the cost significantly to bundle them together. I guess the Zone 2 boarding might be a minor change for those without status, but my impression is that Zone 2 on a WS 737 is effectively the back half of economy, so unless they change the boarding zones, most of economy on a 737 is now Zone 2?
No mention of any benefits for elite members, as currently Gold/Plat/Silver can use their seat selection vouchers or benefits for preferred seats. If this eliminates preferred seating for status members, that's a huge downgrade, especially with WS densifying their 737 economy seating down to a knee-crushing 28-29" pitch.
They make it sound like an enhancement, but it sounds like this could be a major downgrade of seating benefits for status members.
