- tickets stated as direct included a hidden stop and change of plane.
- there was an extra charge for a checked bag.
- the checked bag was promptly lost on my first flight and returned to me after 5 days.
- on one united flight, we had to wait on the tarmac for 1hr45 min while a guy sat each wing of the plane in turn refuelling it with a gas-pump style hose through a port on the wing. This was because the central rapid-fuelling system on the plane was broken.
- interior of aircraft was shabby. In one plane they had retrofitted LED lighting in the cabin, but it was too narrow and so exposed hull insulation and other structures in the gap.
- seats felt much closer together than usual. What on earth do you do if you're above average height in the US?
- price! Unbelievably expensive to fly between cities in the US. In SE Asia or Europe I have travelled between similar sized cities and similar distances for well under half the price in the US and at shorter notice.
What ever the airlines may tell you in the US, from the perspective of an outsider, I'm pretty sure they're ripping you off!
