For me personally, not including the travel to Chicago, it would be 225USD for a less than 5 hour flight from Chicago to Seattle, while the smallest cabin (“roomette”) on an Amtrak would cost 1400USD and take over 46 hours. Even the coach is 280USD.

Edit: I’m seeing the bit about short trips now; I thought that the comment I was replying to was about travel in general. Chicago to Detroit would only be 35USD for ~6h on Amtrak coach (no cabin offered), flight price would be the same as Chicago-Seattle. Train would be cheaper in this case, though without a cabin.

Maybe I’m the odd one out but ime here in the States “omelette” is way more common. I would have assumed that the other is a typo.
