Pros
Flight benefits were great when part of AA, but that changed drastically for those of us that came later. Lots of smart people in Finance who had MBA's. Some interesting work, but may have changed in recent years. MBAs get paid reasonably well compared to overall market, and much higher than ordinary Sabre hires.
Cons
Pretty much the whole company. It runs despite the management and politics. The business model for the CRS portion of the business is being a middleman, and many customers and partners attempt to bypass Sabre. Too much focus on developing new products that customers don't want or don't like using. The name recognition for Sabre severely lacks relative to the portion of the travel industry that it touches. There is limited impact that management and all the planning/analysis they put in place can have on the business. The CRS is just a database where you want to keep costs low for the information going in and going out. However, management did anything but when trying to grow their political organizations. The current senior management is just as clueless now as when they were middle management a few years ago. Politics can be extreme. MBAs have better opportunities for promotions and better pay/raises, though there is still extreme competition within that group, and not the best job to take out of business school, unless you are fanatic about company politics and doing lots of useless work.. Its ridiculous how many MBAs Sabre hires with good salaries, and then chooses to only develop a select group of them almost from day one. Many leave for better jobs/companies with better business models and greater impact. For those who are not hired as MBAs, understand that you won't be paid as much. This is market driven and not unique to Sabre. The Sabre brand is not all that well known, and other employers don't often know what it is, much less understand what the company does.
