Westjet did not have enough staff to provide someone for wheelchair assistance. Much longer line than expected and I had to help my dad and manage the baggage.

The flight from Seattle to San Diego was delayed due to a maintenance problem. Alaska Airlines kept customers in the loop and even brought in another plane, which was new and nice. The staff handled it well.
