Update
Bad news:
1. points.com's $30/trade surcharge on giving Delta miles in trade has returned.
Good news:
2. points.com's 50% bonus for receiving Delta SkyMiles in a trade has also returned, which may be worth more than $30 if the trade involves enough SkyMiles.
3. In a simpler and completely positive development, points.com has apparently started a 20% bonus for receiving AA miles in trade, so anyone with an active posted trade involving AA miles and not Delta will probably want to repost to qualify for the bonus.
Good, but not strictly news:
4. For completeness, I should mention that the 15% bonuses for receiving Aeroplan and JetBlue in trade that began last month are still running.
