News and notes from around the interweb:

• American flight attendants publish an open apology to Nicole Kidman disassociating themselves with the broadside on the actress (meant as an attack on Etihad, in support of US airlines’ complaints about subsidies) put forward by their union.

• American Express no longer reports new cards to credit bureaus as though they have been open as long as your oldest Amex card. Minor point, but adding new American Express cards no longer increases your average account age, which is a small portion of your overall credit score.

• Many – though far from all – American Express cardholders have a sync offer in their account for $20 off $20 at Amazon. Log into American Express and check if you can claim the offer.

• All Silvercar rentals are $49 for the rest of April with promo code SILVER49. This should stack with Silvercar’s $25 bonus for being referred by an existing member, you can sign up with my referral code or leave your own in the comments.

• Does United’s recently improved financial performance signal a turnaround? Their margins are weaker than other airlines and improved unit revenue comes from failing to grow the airline while their profitable routes are vulnerable to competition.

• Cranky Flier explains what’s wrong with the ‘airline quality rating’ and he’s, well, cranky.

• How hard should you touch the video screen on the seat back in front of you? We really should shout economy class etiquette from the roof tops!

• Just what we’ve been needing! A new airline has been authorized to operate domestic flights in Greenland.
