My name is Kontee Thongthai and the confirmation code of my airline ticket is LJ*MRR. I would like to change my departure date from August **th, **** to August *nd, **** or other dates before August *th or as soon as possible (I prefer at least two weeks before August **th, ****). My flight is from Chiang Mai (CNX) to Houston (IAH) operated by EVA airline. How could I do? As you know, with the strike situation of the EVA airline in this period, I quite lack confidence in the airline service. Although, the latest news said that the strike will be ended in this month, I have still felt uncomfortable about the situation because I have to exactly arrive at IAH on this August **th and could NOT be late more than that (I am a student at University of Houston and I have an important class and meeting on August **th, ****). Moreover, I have gained a lot of warning from my friends who gained flight cancellations. Therefore, to make sure that I won’t be late to arrive at IAH than August **, could you please find a new EVA flight or other airlines for me from Chiang Mai (CNX) to Houston (IAH) at least two weeks before August **, **** (It means that I would like to arrive at Houston, Texas before August *, ****.)? In addition, I think I should not also pay any fee or do additional payment for this change.* I appreciate your time and consideration.
