I found that an excellent way to gain insight into the Revenue Management field is through the Practical Revenue Management in Passenger Transportation course.

The content is written by an expert in the industry that had the ability to write in a very user friendly manner seeing that the vocabulary used is easy to understand and because each section begins with an introduction and ends with a summary which makes the work easier to grasp and to see the bigger picture.

I would recommend this course to anyone that is interested in this field even though they might have little to no theoretical knowledge of the industry. I would also recommend this course to someone that has limited time.

I’m looking forward to complete the next course later this year. Mienke Knipe - Vervoerekonomie, Stellenbosch Universiteit, Departement Logistiek. June 2015.

Gary has immense knowledge and experience in the field of revenue management. Also he is well versed with all the current practices happening around the world in RM.

Initially, it was really a tough decision at my end to start up the course as I was based in India and RM concept was not much popular, however Gary convinced and supported me well to start up. He made me understand the RM logics and concepts in very simple language and techniques for which I really started enjoying subject. He acted like a real mentor and cleared each and every single doubt with conviction and always replied my queries without any delay, also was always available on phone for any doubt. One thing I must admire in him is that he is always open for discussions.

The course material prepared by Gary is one of the best you could find in RM world. Also the online RM library, discussions, presentations, conference updates will give a detailed view of RM and what is happening in RM field around the world and keep you updated. Now, with the new course structure one even can understand the difference in practice in RM between a low cost airline and full service airline.

I strongly recommend to everyone who intends or plans to get into the world of RM.

I sincerely thank you for your continued support and extending your full cooperation. In fact, I have managed to crack all positions where you have guided me. I owe a lot of my success to you. Susanta Kumar Sahoo, Revenue Systems R&D Manager, Emirates. May 2015.
