The business seats being compared

These are each airline’s best-scoring documented business aircraft. The fare grid does not identify aircraft, so the seat below is not promised with any fare in the table. Service and food require a separate firsthand review.

Check the aircraft on Aer Lingus

A330-300: 5/10 for the seat. A staggered mix of 1-2-1 and 1-2-2 rows, so roughly 90% of seats reach an aisle directly and the paired seats do not. Un-retrofitted ex-Qatar frames are worse again. Recorded August 30, 2026.

A321neo LR / XLR: 5/10 for the seat. Aer Lingus' own site states 60% of seats have aisle access on this aircraft, which contradicts third-party pages calling it 1-2-1. The carrier's figure is the one used here. Four throne seats are the ones worth chasing. Recorded August 30, 2026.

Check the aircraft on SWISS

A330-300 (legacy staggered cabin): 5/10 for the seat. This legacy A330 seat map alternates 1-2-1 and 2-2-1 rows: some window seats have a neighbor, while solo seats reach the aisle directly. It does not describe the newer A350 SWISS Senses cabin, which is not yet scored in this table. Confirm the configuration and exact seat on your flight. Recorded August 30, 2026.

Compare the fares and the routing

Each row compares the same airports, cabin, travel dates and observation date. It can still compare a nonstop against a connection. Journey times, aircraft, baggage allowances and change rules were not recorded with these fares; check those before treating the price difference as a saving.

Before paying for the ticket

  • Check the exact operating airline and seat map on every long flight, including the return. An airline name or business-class label alone does not guarantee a flat bed or aisle access.
  • Compare total journey time and connection length. A lower fare may buy a much longer trip.
  • Reprice with your bags, preferred seats and change rules included. These observations do not establish that the tickets have identical restrictions.
  • Check other airlines on the route. Being cheaper than the other airline on this page does not establish the cheapest fare in the market.
