I don't think I will raise a stink over that because I have bigger issues to take up with DL over that trip. Plus, for all I know, that lounge might be one of the exceptions for some obscure reason. Nothing works the way it's supposed to at that airport, anyway--or the entire country, for that matter. That's expected.

Off this topic (although part of the same trip), but my bigger issue is that instead of reworking my original fully refundable, changeable, multiple stopover ticket when adding new legs to the trip, DL booked a whole new itinerary instead (on a lower fare class), messing up my upgrades, baggage allowances, and causing me to pay about $500 more than I should have. I didn't immediately realize it. When I called DL about it, one agent told me that even if they had originally booked it correctly as one itinerary, I would lose the international baggage allowances on my domestic legs. I told her it didn't make sense, b/c it's not like I'm going to get rid of some of my luggage on the domestic portions. But she said her supervisor confirmed what she was telling me. I could not believe how mind-blowingly ignorant of their own policies these DL agents can be, including the supervisors.

So see, this lounge thing was just a minor annoyance in comparison.
