After partially completing a flight booking, I got a follow-up call. The person wasn't overly pushy and accepted my explanation when I mentioned that I'd finalize my booking in the next couple of weeks rather than immediately.

The call was legitimate, following up on a flight booking I had partially completed. The caller was respectful and not overly pushy, understanding when I mentioned that I planned to finalize the booking in the next couple of weeks, but not immediately.
