I’ve travelled with Aircoach a few times and has mostly been a pleasant experience. However despite pre booking a ticket I’ve had to wait anywhere from 1-3 hours for the next available bus as there isn’t enough spaces. It’s honestly a gamble and sometimes the drivers can be a bit rude. I’m not sure if this is because i’m young, black or a woman. I’ve noticed they’re a lot kinder to middle aged shire people. Anyways i suggest having at least 2 buses per route that way people aren’t waiting in the rain and those who couldn’t precook for whatever reason can still make their journey at desired time :)
