Caught a 2 a.m. flight back home. Landed at the shit terminal that's not connected to the main ones. So that's another hour and a half bus ride back to the apartment instead of a 45 mins train ride.
For all the hype about the Changi Jewel in the news these days, i wish someone in the government would realize having T4 and T5 not connected to the first three terminals makes them really inconvenient.
