We already have an airline booking site but what I am looking for is some one to provide me an single XML interface which has standardised a screen scrape of the booking processes of 5 different airline websites. This will need to include pricing, availability returns, passing of credit card details to the airline's website and returning to the XML interface the confirmation numbers of each booking once the booking is completed on the airline's website. Note some of the airline websites maybe via the airline's B2B website after username & password login pages.
Once I have the first 5 working and all is well this will continue as an ongoing project with 5 more airlines at a time.
