Hi Kevin, I just did my own version of this challenge and I'm surprised by the number of things I didn't even consider.

For example, I completely forgot that SMS message was another viable form of notification.

But you assured me that normally in situations like this, airlines would notify users in more than one way.

I know you mentioned at the end that users can contact the airline in other ways to figure out their next steps, but do you think the text should reflect that?

For example, instead of saying "See our service desk to reschedule your flight" it could say something along the lines of "You can contact us to reschedule your flight". That way it prompts them to click "Contact Us" and then they'd be given options on what they feel is best as opposed to thinking they have to go find a service desk.

Other than that, great piece! Thanks for the article.
