Most probably a logotype, not a font, especially looking at the T. But Futura Extra Bold is on the right track.

There are a lot of sans faces that are very close to this look. Even Helvetica looks close.

Based on your new post, I’d say it’s Helvetica, but customised (the T and R stand out the most).

The United logo is a modified version of Futura Bold. When
United spun off Ted, they kept Futura Bold, but used U&lc.

(TedEx anyone?)

Upon a second look, that e in Ted is not Futura. Or if it is,
Pentagram modified that too.

Ted looks more like Akzidenz Grotesk than Futura to me, the angle at which the lowercase ‘e’ ends kinda gives it away.
