Bright but not blinding. The true white and true white share enough warmth that the whole look reads deliberate, not accidental. The collar holds its shape all day without that wilted-polo look. Boarding group 2. You didn't check a bag and you don't look like it. When your outfit doesn't wrinkle, you stop worrying about the flight. You just take it.
Finish with clean white leather sneakers and a structured weekender in tan or cognac.
