That's irrelevent in terms of when you could plan a pre-season Europe trip.
Indeed, not qualifying for the Europa League would make it harder to organise.
[edit] Actually I have made an error with the legue cup dates. Hearts and Dundee Utd play the first game in the League Cup Group stages a day later than we play in Europe, so there is no difference if we qualify or not in terms of playing our first competitive game [/edit]
You could argue they have this "European Pre-season friendly" when they go to Ireland and play Connah's Quay Nomads on 29th June
