There's really no way of predicting which stand it will come in on. The vast majority of flights I meet coming in from EDI or GLA come in at one of the doors at gate 55, but it's unpredictable.

The only thing I would say is that with an ETA of 1005 there are 777's on quite a few of the international stands which means more chance of it coming into 55 somewhere and thus using a jetty to disembark.

Sorry I can't give you specific advice.
