While we waited vs. While we were waiting

[Jupiter]

Hi teachers,

I met Tom at the airport a few weeks ago. We had a chat while we waited/while we were waiting for our flight.

Which one is correct?

Thanks in advance

Clould you tell me the reason why the first option sounds better?

it´s shorter ...more general..while we were waiting for our flight, the most extraordinary thing happened! A baby elephant walked past!
