I use the flyertalk frequent flier forum occasionally for unbiased airline promotions and knowledge. Flyertalk is not awfully good for luxury hotel reviews largely because of the lack of decent photos, but for airline bookings, particularly for American flight bookings like Delta Airlines, it can prove a very useful source of knowledge, enabling you to get to your luxury hotel with more money left to spend once you arrive!
As an example I have put together a three step guide on getting a discount on any Delta Airline bookings that you might want to make. You can use the same set of guildlines for any airline booking:
1. Join Delta Skyclub to Collect Delta Skymiles.
2. Use a cash back site for any bookings, cashback monitor will tell you which is the best option in the USA. In the UK Topcashback and Quidco tend to be good options.
3. Finally check the Delta Promotions thread on Flyertalk, which can require some perserverence, and check for any relevant Delta promotions that you might be able to apply.
I will not even try to detail each and every promotion, there are just too many and they change too often which is why a forum like flyertalk is useful (if time consuming). Happy flying!
