I don't know the ins and outs of DL since I'm a US person. I have a buddy who is relocating to HNL and us currently stuck at SEA waiting for DL2237. Originally scheduled at 17:35, it's now listed for 00:30 and it's an MX issue. I don't know if there's an aircraft swap involved or what at this point. He got meal vouchers, at least. Just wondering if anyone has any suggestions or can provide more detail about the flight. I was also going to see if he's upgrade eligible and donate my miles for the segment. Assuming the stars aligned with fare class and availability (unlikely at this point, I'm aware), would this be possible at the gate with me on the phone with my friend?
