Shareholders at the Irish airline expressed their frustration at management on Thursday by re-electing Bonderman by a narrower margin than last year after a year overshadowed by Ryanair's worst-ever strikes.

Bonderman told journalists he thought the criticism of the board was "way off base" but declined to comment on how long he would stay on as chairman.
