CNAME delegation

smetrics.southwest.com → southwest.com.ssl.sc.omtrdc.net
soptimize.southwest.com → southwestairlines.tt.omtrdc.net

DNS delegation identifies infrastructure; it does not prove which browser code ran.

Instrumented frames: 2
Google Ads observed: No
Transmission evidence: Not validated

Legacy transmission hints are excluded. A request after an API call does not establish that the extracted value was sent.
