• Will my seat have a powerport and what kind of plug do I need?

See SeatGuru or SeatExpert for information on which seats have powerports. AA uses “cigarette style” DC powerports on the vast majority of its planes, which are rated up to 75 watts. Various specific and universal power adaptors are available for use with laptops and other electronic devices. As of early 2009, a small number of newly delivered 737-800 (38D) and retrofitted international configuration 757-200 (75L) aircraft have regular AC outlets in every row of the aircraft.

DC powerports on domestic 757-200 (752) aircraft have been disabled since Sep 1, 2010 due to an undisclosed problem. DC powerports are also disabled in rows 17-44 of the coach cabin of most 767-300 (763) aircraft as of Jan 15, 2011. Both are expected to be repaired by the end of 2011. DC powerports were also disabled on all 767-200 (762) aircraft from Jan 15, 2011 – May 20, 2011 but have all now been restored.
