I tried multiple times with other agents. I had originally placed it on hold an dgenerated PNR last night and they asked me to call back in the morning for payment after all fees had been calculated. On calling back they're saying it is not bookable as 1 single PNR. They want to issue 1 PNR for LAS-EWR for 15k miles and then 1 PNR for EWR-DTW for 5k miles. They're also saying that this would not be connected in any way which would mean my 1 hour connection in EWR would be in danger if I have to claim and re check baggage. In any case being on 2 different PNRs I would not have any IRROPS protection also as explained by them.

It is just a transit layover for a Origin - Destination journey of 1749 miles which should allow upto 3 flight segments anyway. However they're not agreeing to this logic and saying this is backtracking and they can't ticket it.

I have had to email them and they've said I'll receive a clarification from them. I have given up hope and just booked a direct LAS-DTW on Delta using my HDFC Diners points. I was just hoping to use some of these useless AI miles that I seem to be swimming in.
