Trying to get current info - flying thru LAX next week connecting from my Alaska flight (arriving Terminal 6) to AA flight (departing from Term 4) - have done this in past via shuttle bus with horrible service and horrible personnel; excited to hear about opening of tunnels and understand how they work from internet search but has anyone used them recently? And was the bus service between T4 and T6 actually discontinued? And if for some reason my flight out of LAX is American Eagle and leaves from Gate 44(A-J) shouldn't I just take the shuttle bus (if available) from T-6 since Gate 44 is ONLY accessible by bus? Or should I walk tunnels from T-6 to T-4 and then get on shuttle to Gate 44?
