AbstractThe current study compares the realization of the speech acts of complaints and responding to complaints by Arabsversus Westerners in the X accounts of British Airways versus Saudi Airlines. We compiled 400 posts from the X accounts of the twoairlines and coded them for complaint and complaint-response strategies as well as external and internal modifiers. The results ofthe Chi-square tests show that the Western customers of the British Airways used significantly more disapproval and accusationstrategies than the Arab customers of the Saudi Airlines while the latter customers showed a stronger preference to employ theblame strategy in addition to directive acts. As for the responses to complaints, the representatives of the British Airwaysshowed a stronger tendency to accept complaints through offering repairs, admitting responsibility, and excusing oneself whereasthe representatives of the Saudi Airlines preferred to employ partial-acceptance strategies. The results are interpreted in lightof the existing literature and the Mixed Games Model.
