Sit on the Left side of the plane for the best views on flights from Shannon to Boston. The left side wins overall. The Shannon Estuary and Cliffs of Moher departure is genuinely spectacular, and during the transatlantic cruise the left side faces south, giving occasional views of the southern tip of Greenland's ice sheet if routing takes you near it. On arrival, you lose a little to the right side, but the departure experience tips the balance.

As you approach North America, the coast of Nova Scotia and the Bay of Fundy become visible, followed by the Gulf of Maine before descending toward Boston.
