Some airlines can’t even get Apple Wallet right yet :(
My local airline’s website is also incompetently developed. My SO couldn’t add boarding passes to Apple Wallet because the URL in the email was malformed, and on top of that, their website kept giving us same boarding pass with my name on it when we clicked on our individual names. The only place with the correct boarding passes was the first confirmation email they sent us, which had some deep-fried-esque low quality jpegs.
