As RichardMEL suggested above, what you've described just how Qantas "blocks" OLCI. The system will say you've checked in but your check-in goes into a verification required state and you can't proceed any further to select a seat or issue the boarding passes. This exact same scenario will also happen to you if you click "Yes" on travelling with dangerous goods or if you fail automated visa checks. Why do they also block the seat selection and not just hold the boarding pass? Who knows.I thought OLCI was blocked but I've now proven that it's not blocked but I can't print boarding pass.
Please answer the question on why I cannot choose seats during this OLCI process but Qantas still happy to take my money if I choose to pay for those seats.
Unfortunately by the time you've noticed this, due to the imminent departure the flight will now be under airport control meaning no telephone agent will be able to do anything to assist as their authority to make such changes in the system is removed and restricted to airport staff only.
Am I surprised about the lack of consistency of being able to still do paid seat selection even though the OLCI seat selection is blocked? Having read through most of the QF IT gripes thread, not really.
