She'd always wanted to go to Thailand
In this recording, the speaker is pronouncing the T, but is kind of reduced, as JamesK's answer says.
He wanted that job so badly he was willing to kill for it.
In this one, there's neither a glottal stop, nor a flap (as the other answers suggest). It's a case where Americans usually drop the T entirely.
In most--if not all--American accents, when a stressed syllable ends in an N and the next unstressed syllable starts with a T, the T is usually dropped, so ˈin.ter.net becomes innernet, ˈcoun.ter becomes counner, ˈtwen.ty becomes twenni, ˈwan.ted becomes wannid etc., so you're hearing it corrrectly: "/ˈwɒnɪd/".
