I'm finding myself wishing I had tried to book one of the last flights even though I had approximately 630 Mad Dog flights over the years. I have certainly experienced them pretty thoroughly, but being a part of this last send-off, muted as it is, would have been cool.
My first ride was either a Delta Widget or a Continental Saul Bass - wish I'd kept better records back then. I ended up flying on quite a few other Delta and Continental birds in all their liveries, but the bulk of that 630 was on American's silver fleet in and out of Dallas. I managed to fly almost 70% of all the ones AA ever had. Top Dogs with 6 flights each - N564AA and N972TW. I got 2 MD-87 flights on Aeromexico. My last MD-88 flight was on N975DL in 2018, and my last ever Mad Dog now looks like it was MD-90 N936DN about a year ago. Although I suppose it's likely I'll still manage some 717 rides in the not-too-distant future, the full MD experience is now behind me.
I'm gonna miss the comfort of the 2-seat side (A220 here I come), the quiet ride up front (even as I savored the JT8D whine), and the sturdy feel of a Douglas. Missing seatback PTV's never bothered me - if I had to say anything negative it would be the lack of modern power outlets.
Anyway, I think the skies will be a less interesting place from now on. Rest in peace, old friends.
