Didn’t like not getting my seat until check in. Especially since I was flying w my 7 year old. Wasn’t sure we would be put together.

Pilot did an amazing job keeping us safe by aborting landing in heavy wind at Seattle airport and flew to Vancouver. He had big challenges on all ends and really did a fantastic job. We all applauded when we finally got back to Seattle. Bravo!
