Hi...I'm looking for information for on-line GDS- Sabre- Amadeus- Nexion- ICtravel- comparisons and advice on where to start training to work at home. I was a corporate travel agent for 14 years but have been out of the business for the last 15. I've read info on sabretravelnetwork and briaini academic. All advice and information on the best way to get started would be greatly appreciated ! Thanks.
