1. American Express has new, heightened bonuses available via the Random Number Generator™ (which can be played by trying different browsers, going incognito, using a mobile device, hitting the landing page through a search engine, or by tossing cheese up into the air between each keystroke). The offers:

    Blue Business Plus bonus of 50,000 Membership Rewards after $8,000 spend in three months.
    Blue Business Cash bonus of $500 after $8,000 spend in three months

    There are variations of these offers available via referral with slightly higher spend requirements of $10,000 in three months too, and are those are much better for the referrer. (Thanks to robdajewels)
  2. American Express Membership Rewards has a targeted 20% transfer bonus to Etihad Guest miles through April 4. I wasn’t targeted, but this program is a sleeper program and one of the only ones I’d transfer a few miles into speculatively.
  3. Two airline shopping portal have new spend bonuses:

    Southwest: 1,000 Rapid Rewards after $300 or more in spend through March 18
    AA: 500 AAdvantage miles after $150 or more in spend through March 11

    In other non-news, giftcards.com remains available on major shopping portals.
  4. Turkish Miles and Smiles has a 20% rebate on award tickets booked on Turkish metal booked by August 31 for tickets booked by the mileage account holder. Tickets booked before yesterday won’t qualify though.

    The rebated miles expire at the end of 2025, regardless of the other mileage expiration dates or activity.

An child suffers the unfortunate side effect of the American Express Random Number Generator™ game.
