Steps
Open a stateful Sabre SOAP session with OTA_SessionCreateRQ
Send OTA_VehAvailRateLLSRQ with pickup location (IATA airport code), pickup and drop-off date/time, and renter age
Parse OTA_VehAvailRateLLSRS to extract VehAvailCore elements with EstimatedTotalRate and vehicle category codes
Filter by category (car class SCAR, MCAR, FCAR, etc.) and identify included vs. excluded mileage
Confirm the rate with OTA_VehResCreateLLSRQ providing renter name, loyalty number, and credit card guarantee
Store the confirmation number and rate code returned in OTA_VehResCreateLLSRS
Known gotchas
Sabre car rates include a rate qualifier code that must be echoed in the reservation request; dropping it causes the booking to default to the published walk-up rate instead of the negotiated rate
Estimated total rates in Sabre car availability are pre-tax; mandatory fees (airport concession fee, vehicle license fee) are added at checkout and can significantly increase the final amount
One-way rentals (different pickup and drop-off locations) require a one-way surcharge field in the request; omitting it results in a rate quote that will not be honored at the counter
