This has been going for a couple of years now. What exactly were to happen if Åland rejected the treaty (the Finnish parliament has already voted to ratify it) seems to be unclear. The former president of the Finnish supreme court, Leif Sévon, even suggested Åland could end up completely outside of EU if it rejected the treaty (Ålandstidningen ). That was perceived as bit of a threat in some Åland quarters; former Åland member of the Finnish parliament and prime minister of the Åland government Roger Jansson even going so far as suggesting that the perception that the autonomy is being trampled upon would lead to significantly increased support for the separatist party Future of Åland, which received about 8% of the votes in the last election.

Ultimately it's not likely that the Lagting (the Åland parliament) will reject the treaty, but of course the Åland government will attempt to get every concession they can out of the negotiations. It was never a realistic proposition that Åland would get a seat in the EU parliament, unless it would be in addition to the seats Finland already has.
