Useless App ever

1348861575: why can the confirmation email display the barcode for the bus driver to scan?

The has a link to vow the barcode, the link opens a website, which asked if you want to open the barcode in apple mail, upon clicking it it open the confirmation e-mail, and the circus goes on and on. There is no convenience in using this app. I can only hope my Robin Island trip doesn’t follow the same logic
