Best Web Service hubs

Hi all,

I'm looking for some web service providers. Specifically, those related 
with  "airplane tickets": timetables, prizes, etc.
But I have not found anyone!!!

I've searched at the hubs I know:

    * www.salcentral.com
    * www.xmethods.com
    * www.webservicex.net
    * www.remotemethods.com

And used some UDDI Browsers (WSDP 1.3 and SourceForge's UDDI Browser) to 
search at the typical UDDI registries:

    * IBM (http://uddi.ibm.com/ubr/inquiryapi)
    * MS (http://uddi.microsoft.com/inquire and
      http://uddi.rte.microsoft.com/inquire)
    * HP (http://uddi.hp.com/ubr/inquire)
    * SAP (http://uddi.sap.com/UDDI/api/inquiry)

Do you know some other hub or UDDI registry?

Thanks a lot,

-Mariano
