We recommend using Google Flights to find your best dates, and then booking your flights on the airline’s website. Direct airline bookings tend to be more reliable if your flight is delayed, canceled or has a booking change.

For a round-trip flight from Boston to Dublin in May, Google Flights only offers two Aer Lingus flights. One costs $501, and the other is slightly more expensive at $534.

If you opt for the $501 flight, Aer Lingus offers a returning flight that takes off at 11:45 a.m. May 8.

While the round-trip fare from Boston to Dublin is $501 if you book directly with Aer Lingus, Google Flights may list the fare as $483 instead.

Sometimes, Google Flights advertises a different fare compared to what you would find on an airline’s website due to the availability of third-party booking options. In this case, Google Flights features a variety of third-party booking sites for this flight, but you’d be better off booking your flights on Aer Lingus’ website.

While you’re saving a ton on airfare with these deals, remember that they only extend to basic economy, which can be restrictive. Aer Lingus’ basic economy fare, known as its Saver fare, only allows passengers to bring a carry-on and includes a complimentary meal. Seat selection, checked baggage and ticket changes have additional fees.

Seat selection costs anywhere from $29.99 to $114.99 — the most expensive seats on board have the most legroom and are located in the exit rows of the aircraft.

Aer Lingus also has a range of prices for checked baggage. For example, the lightest possible checked baggage — which would weigh 44 pounds maximum — would cost $109.98 round trip.
