How about one way with Aer Lingus, and home with Ryanair? Watch the baggage allowance though. Only 15kg IN TOTAL check in with Ryanair, which is not a lot...
If its not an error then God help EI for employing such an idiot who loads those prices, which are four times the cost of an outboundflight, or four times the cost of getting back from Tenerife.
Aer Lingus's one-way flight back in Nov/Dec is more than the cost of a one-week package holiday, which includes a return flight with no hidden fees, apartment, transfers for about 350 euros for much of Nov and Dec.
However, i ain't pointing it out to EI. As a travel agent it suits me fine if airlines websites throw up crazy those prices !
If you want to fly with Aer Lingus return to Brussels in Nov 2009 the outward taxes are €19.99 and back €29.99.
If you want to fly to Brussels in April 2010 the outward taxes are €35.75 and the return taxes are €36.67.
Aer Lingus have a new 20% off Summer Sale starting today. However I see that they are up to their usual tricks again. Last week the taxes that they were charging in their previous sale for outward flights was €29 but today they have put the taxes up to €38 for the outward journey.
