When LX was merged to LH I booked on the LX homepage an e-ticket on an OS Codeshareflight from VIE to ZRH.
First I went to OS Check In and they didnīt find any booking. Afterwards I had to go to the LX ticket counter and they printed out the paper ticket. I was not allowed to check in on the LX counter, I had to go to the OS check in counter. In Vienna and at Zurich I was not allowed to enter the LX Lounge.
Now there is the lounge access available, but I am also suprised, that the problem with the e-ticket and printing out a paper ticket is not solved yet.
