Head to head

Aer Lingus vs TAP Air Portugal

TAP Air Portugal scores 9/10 against Aer Lingus at 7.3/10 on seat, screens, lounge and fare.

Best product each one flies

Scored on what can be verified. Service, food and ground recovery are absent deliberately: they need someone in the seat, and they live in the reviews rather than here.

One caveat on the Value line, stated rather than buried: the cabin scores describe a business product and the fares behind Value are economy. A carrier that prices economy aggressively generally prices business the same way, but they are different products. Read Value as how an airline prices against its competitors, not as what its business seat costs.

What happens if the aircraft swaps

Both carriers are paying-the-same-fare-either-way propositions on some frames. The worst product each one flies:

Aer Lingus

A330-300

Seat: 5/10
IFE: 8/10
Lounge & bags: 10/10
Value: 6/10
Product score: 7.3/10

TAP Air Portugal

A321LR · flown by Jon

Seat: 5/10
IFE: 8/10
Lounge & bags: 10/10
Value: 10/10
Product score: 8.3/10

Aer Lingus: 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.

TAP Air Portugal: Solo throne seats in the 1-1 rows; the 2-2 rows require stepping over a neighbor.
