is everything alright ?   yes , everything is fine .   what took so long ? I thought your flight was supposed to arrive 3 hours ago !   didn't they announce that our flight was delayed ?   I didn't hear anything about a delay . I thought everything was running on time . What happened ?   we boarded the plane on time , but then we were held up for almost an hour due to a maintenance problem .   then what ? Your plane was three hours late !   we finally took off , but about 30 minutes later , the captain came on the loudspeaker to warn us that there would be some bad turbulence for most of the flight .
