I'm flying PDX-SEA-AMS-BUD this coming Saturday, and I'm starting to get a little worried about my Seattle connection right now. DL 4790 (my initial leg) has a so-so record as far as being strictly on time according to FlightAware, but I didn't think that that was too worrying given that it's a quick flight and my scheduled layover is about an hour and a half. But it looks like tonight's flight left Portland a good two hours late, so I would have totally missed my flight to Amsterdam had I left this weekend instead. One of my coworkers recently told me that the same thing almost happened to him as he flew PDX-SEA-LHR a couple of months ago, except that he arrived early enough to take the preceding flight to Seattle and paid extra to get onto it, not even knowing at the time that 4790 would've gotten him there too late to make his connection.

So, do you guys know what my options would be in this situation if it happens to me? I assume that Delta would comp me for my hotel room and meals until I could get on a flight the next day, but obviously less than ideal. QX has PDX-SEA flights on Q400s every half-hour, but even though I could get Alaska to interline my checked bag to Budapest, am I right to assume that Delta wouldn't do anything to get me onto one of those flights or comp me afterwards if I bought last-minute tickets to make my connection?
