Hello. I recently redeemed an award ticket using SQ miles. The return flights are MEX-CUN-IST-SIN, with the MEX-CUN-IST leg operated by TK and IST-SIN by SQ. I understand that TK does not use Amadeus and I cannot manage the booking using SQ's booking reference on TK's website.

Is there any other way to see this booking on TK's website or app?

If I cannot manage this booking on TK's website, how can I check with TK to see if the flights are tickted and to check the baggage allowance?

Thanks.
