Galileo, Worldspan, Apollo, and Amadeus are four of the major Global Distribution Systems (GDS) used in the travel industry. Each GDS has its own unique format for entering commands and accessing travel information. Here is a basic comparison guide between the four GDSs:

1. Galileo: Galileo’s format entries use cryptic commands that are specific to the system. For example, to check flight availability, a user would enter “FQBB1DECJFKMIA” where “FQ” indicates a fare quote, “BB” is the airline carrier code, “1” indicates the number of passengers, “DEC” is the departure date, and “JFKMIA” is the origin and destination airports.
2. Worldspan: Worldspan uses a more user-friendly format with natural language entries. For example, to check flight availability, a user would enter “1AVAILDLNYC10DECJFKLAX” where “1” is the number of passengers, “AVAIL” is the availability command, “DL” is the airline carrier code, “NYC” is the departure city, “10DEC” is the departure date, “JFK” is the departure airport code, and “LAX” is the destination airport code.
3. Apollo: Apollo uses a command-driven format similar to Galileo. For example, to check flight availability, a user would enter “FQBB1DECJFKMIA” which is the same command format as Galileo.
4. Amadeus: Amadeus uses a more intuitive format that is based on codes and abbreviations. For example, to check flight availability, a user would enter “FF JFKMIA 10DEC” where “FF” indicates a fare quote, “JFKMIA” is the origin and destination airports, and “10DEC” is the departure date.

Overall, each GDS has its own strengths and weaknesses, and the format entries can vary significantly between them. Travel agents and other industry professionals typically receive training and certification on a specific GDS, allowing them to become proficient in its commands and syntax.
