I fly EIR/RE fairly regularly and whilst I admit some of the cabin interiors could do with a refresh, I have ABSOLUTE confidence in the maintenance of the aircraft and professionalism of the crews in the highly unlikely event of something untoward occurring. I would be more likely to avoid another airline where I have serious doubts about cabin crew abilities away from sales and am concerned at communication issues on UK/Irish routes where the majority of crew have English as a second language and cannot make themselves understood over the PA or when giving out simple instructions during cabin securing, resulting in frustration on both sides and subsequent arguments.
EI mainline crew are generally second to none in both professionalism and courtesy.
