一般係咪買6pm後嘅回港機票?因為見學校寫「It is most often the case that students take evening flights (i.e. departing 6pm or later) and coaches depart from Concord around 11am to enable students to catch such evening flights.」
返UK機票又點買呢?係咪只可買早上到UK嘅機位?
「 Students will be met by our staff at Heathrow in the Terminal 3 arrivals lounge between 0600 & 0900 」
though it was 10 years ago, see if it can provide you some insights.
