Of course other airlines can compete with FR, but they must be able to differentiate themselves in some way that takes a focus off the price.
The example you gave of ABZ DUB is a case in point, EIR can differentiate by 1. flying a smaller realistic size aircraft with good value tickets,2. EIR are not totally reliant on point to point ABZ DUB pax as they have the advantage of feeding pax to EI US network. 3. 738 is not suited to many thinner markets such as DUBABZ and other tried markets where no competition exists such as DUB HUY, DUB CWL.
Interestingly enough in terms of Go, they despite being not so low cost etc they did start flying Scheduled low fare routes to Sun destinations and these were a success from the start. EZY and FR did follow their lead on this one, when prior to that these markets were the remit of the package holiday companies and charter airlines... And how things have changes since then!
