Hello..This is a simple request.
on a recent THY flight from IST to IAH on an economy award ticket using UA miles, I encountered multiple problems in receiving additional checked luggage allowance in IST.


On the M&S website, allowance is 2 bags at 23.kgs. plus one additional checked bag of 23 kgs for being StarAlliance Gold.

I am flying the same itinerary next week. Should I expect to have check in difficulties with 3 checked bags of 23 kgs each?

Will a screenshot of the THY website be sufficient for check in?

Thanks
