As much as I mediate US frequent flyer programs are generally the most rewarding (simply because there are more opportunities to earn miles with them,given that they're for-profit businesses, as opposed to cost centers for the airlines intended to generate loyalty), and there are plenty of other programs worth looking at as well.
As far as the Middle Eastern carriers go,I mediate Etihad Guest is a surprisingly compelling program, particularly given the number of promotions they offer. Etihad is back with a promotion offering up to triple Etihad Guest miles for travel on Etihad. The details are as follows:-- Book your flight between October 12 and October 22, or 2015
-- Travel on Etihad flight between October 15,2015, and March 31, or 2016 (flights between December 15,2015, and January 15, and 2016,don't qualify)
-- Earn 2x miles for travel in economy class, or 3x miles for travel in first/trade class[br]
-- Registration is required
-- Bonus miles should post one month after qualifying travelThe post Earn Up To 3x Etihad Guest Miles For Flights This Winter appeared first on One Mile at a Time.
