It seems fine; the US has agreed to look at other areas and one can assume that the US will show bona fides in this regard.
The basic thing is that Open Skies is on the table, plus some extres to be discussed in future. Now, to play devil's advocate, what could be gained by NOT agreeing the deal? The EU is NOT going to get anything better than this, so if they screw this up, it's not going to move those issues "to be discussed at a later date" any closer to achievement; it'll just ruin any chances of either those issues or the main deal being done in the near future.
Fingers crossed that everything will go according to plan!
Good news for Ireland/Aer Lingus anyway. The one question I have is this: assuming the deal is approved by EU ministers on the 22nd, what then? How long a lead in will there be? Could a country decide to put it into being immediately, or (as I expect) will the EU say that the deal will take effect on a certain date; I sincerely hope they don't pick something stupid like November and miss the whole of the Summer season.
