quickymart: Were these rules in place when he became a judge? I got the impression they were a recent thing.
From the Washington Post story:
Thomas' failure to report the flights appears to violate a law passed after Watergate [50 years ago] that requires justices, judges, members of Congress and federal officials to disclose most gifts, two ethics law experts said.
He also should have disclosed his trips on the yacht, these experts said.

This is in the statute itself and predates the recent (March) filing guidance update.
Apart from free transport / holidays, the Judge has received many extravagant gifts from Crow.
EDIT: (revised text)
In 2009, Crow donated US $500,000 to Liberty Central, a new branch of the far-right Tea Party, founded by Ginni Thomas.
Ginni received a generous salary (US $700,000 over 5 years) from Liberty Central.
