Etihad Airways sent out an email about their new worldwide economy & business class sale at up to 30% off, but there was some far more interesting on the email as well.
Etihad Guest members can earn double miles for both economy and business class for flights taken between March 3 and December 12, 2015. Registration is required by March 3.
Note that it is unclear from the promotion terms and conditions if there is a booking date requirement for this offer as well. There are no mentions of any.
Etihad Airways rarely has bonus miles offers for flights in economy (often for business and first class). It makes sense to sign up for this offer and hope for the best, as there are no booking date requirements mentioned on the terms and conditions. Only that you need to register for this by March 3.
Here are the terms and conditions of this offer:
This offer is open to Etihad Guest members only. Registration is mandatory to receive the bonus miles and is valid till 3 March 2015. The bonus miles will be offered on EY operated flights and does not include redemption flights or code share flights. Bonus miles earned will be Etihad Guest miles and not tier miles. This promotion is not in conjunction with any other promotion of Etihad Guest or Etihad Airways. Miles will be credited on a monthly basis. No bonus tier segments will be credited. Each passenger must register separately to be eligible for the offer.
