The budget airline from Ireland is criticized by travellers for the low quality of its services, according to a survey conducted by Travelzoo. Rather unsurprisingly, Europeans tend to favor their national carriers.

Among respondents, 22% of the French, 38% of the Germans, 48% of the Brits and 56% of the Spaniards admitted that Ryanair was the airline they liked the least.

Conversely, the respondents' favorite carriers showed a nationalistic bias, since 22% of the French went for Air France, 30% of the Germans favored Lufthansa, 21% of the Brits opted for British Airways, and 16% of the Spanish selected Iberia.

Respondents mentioned comfort, price transparency and amenities on board to justify their choices, according to Travelzoo.

The survey was conducted online in October 2012 among 5,360 Travelzoo subscribers.
