"Suitable accomodation" applies only to facilities that are used to extend the duty period, ie: split duty...since airport stby does not allow them to extend your duty period, as neither does the lounge...then the "adequate" and "suitable" accomodation proviso in OMA does not apply when on airport stby, or lounge "rest".... you are in fact on duty and the clock is ticking...so when on airport stby, be sure to include that time spent against your duty time period limitation...and the limitation is based on the LOCAL TIME REPORTING FOR DUTY which is when you signed on for airport stby....enjoy it...not convinced it will solve anything, just burn 4hrs off your duty period that could have otherwise been rest....
