Just got an e-mail from WS announcing that many top-tier privileges will be be available when flying DL. As a Gold, here's what they told me I'll get when flying DL:
- Complimentary preferred seat access
- Two checked bags
- Priority check-in and bag drop, baggage handling, security and boarding
- Lounge access to Delta Sky ClubŪ when your trip includes WestJet or Delta flights between the US and Canada
One guest is allowed lounge access.
Downside is that one's WS Rewards number needs to be on the file, which means any DL segments will earn at a crappy rate.
