Crew very late, sat on plane told needed to de ice, 11/2 hours sat. No speaker explanation during wait. Next flight was delayed 45 minutes, then told another 1/2 hour wait, no crew AGAIN...... had to wait for them. Another 1/2 hour wait. Neither crew apologized or anything. Very very dissapointed. My mother 83 was very uncomfortable sitting plus my sister and I have bad backs. Planning on taking mom to Hawaii for her dream trip but doubt delta.
