Anyone looking for a good fare from the US to Spain should have a look at the Aer Lingus website. They have some big discounts on fares to Dublin, from where you can connect with Ryanair to places like Biarritz and Madrid.
Aer Lingus Sale? But will Ryanair buy them!
Seriously I usually fly with Aer Lingus or Iberia to Madrid/Barcelona and connect to Pamplona with my bikes. Would be afraid to ry Ryanair with bikes.
Its getting harder and harder to bring bikes by plane. Very frustrating.
