I just booked a flight with China Eastern Airlines and I noticed that one of the segments is Class Q. Unfortunately this class does not receive any MQM's with Delta. Is there any way to upgrade the class? For example, could I pay a little extra for a better seat? It's a long flight from Shanghai to Toronto so I would love to be able to get those miles. I'm a little new to this so I'm not entirely sure what the class letters represent.
