Apologies if there is a similar thread. I have tried searching but can't seem to find an answer to this question.

Found a cheap discounted business class fare on two separate airlines on Orbitz. Am wondering whether purchasing though Orbitz would trigger the 5 points per dollar spent with Amex. Has anyone tried booking on Orbitz with Amex Plat before? There seems to be conflicting replies online.

Would that purchase code as buying directly with an airline and trigger the 5 points per dollar spent? Thank you!
