user: what does 'receipt required for checkin' mean when trying to check in with your app?
agent: Hi Dan, I would just recommend taking your card used for payment along with the confirmation. Have a great flight!
user: I paid with points. It doesn't let me check in even.
agent: When paying with points, you should still have a confirmation that totals the taxes you have paid. If you can DM your booking details through, I can certainly take a look for you🙂
user: It's an error on the check-in. How can I show a receipt to a mobile check in? Your IT dept constantly let you down.
agent: Sorry Dan, I thought it had to be produced at check in, I didn't realise this was the main issue. In honesty this isn't something we can alter here so you will need to check in at the airport. Sorry for any inconvenience on this occasion
user: There has been endless inconvenience with this booking. Very disappointing
agent: You would be welcome to leave some feedback and someone will get back to you about the issues you have faced
