Fine except for app. Couldn’t check in online - kept saying I couldn’t check in until the morning after my flight. On second leg I could check in but couldn’t get my boarding pass into my wallet. Thankfully I took a screenshot of it because I couldn’t retrieve it when we boarded - the app prohibited it.
