MRTで空港についてチェックインしようとしたら、ターミナル4は→BUS❗️

3年前に出来たターミナルらしいですが、エアアジア他のLCCとキャセイ、KOREAN AIRなどがこちらを利用するようです。
結構離れてますが、空いていて手続き自体はスムーズ(^^) https://t.co/69BvZAyyYR

It seems that the post you provided does not mention anything related to maintenance report feedback for a public flat house. The words used in the post are "mrt", "bus", "lcc", and "korean air", which do not appear to be related to maintenance or public housing. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
