AL - WN used to fly HSV-BHM and I think the flight continued on to Mobile or Montgomery.
OH - CLE used to be an actual hub for Continental and I think they had some intra-state flights.
KY - Similarly, CVG was a Delta hub and they had a pretty extensive regional network via Comair.

just last month I did SEA<>GEG on the retirement flight of the Alaska (Horizon) Dash 8-400

in chronological order here are my first interstate legs:

1. CA (LAX-SFO, Western, Lockheed Electra, 1961) (most recent SFO-LAX was the VX farewell flight in Apr 2018, that was my 60th flight between the LA area and the Bay area in one direction or the other)
2. NY (ELM-ITH, Mohawk, Fairchild Hiller FH-227B, 1971) (19x thru 1976)
3. MA (EWB-HYA, Air New England, DC-3, 1973)
4. CO (DEN-GJT, Frontier, 737, 1973)
5. IN (EVV-IND, Delta, D9S, 1974)

14. OR (PDX-SLE, United, 737, 1979)
15. US Virgin Islands (SPB-SSB, Antilles Air Boats, Grumman Goose, 1979) (yeah, I know, territory rather than state)

For a giggle I thought I'd map out my internal flights within Alaska, not counting numerous air taxi and charter flights. Here's the map -

Probably incomplete, memory fades.

What carrier?

LAX-VIS wasn't much longer.

Does UX still serve VIS? It was an E120 t-prop from LAX.

No one serves VIS anymore, they opted to take a cash payment from the federal government in lieu of EAS service. They have a 6x daily shuttle service to FAT, which is probably sufficient.

United.

Wilmington/ILG had service from Eastern (1960s - 70s) and United (~1983-84); not sure who if anybody may have preceded Frontier, but I seem to recall that their inaugural was quite a big thing because the state hadn’t had much if any service for many years

Self:
CA, TX, WA, HI, OH.

Trying to think if a flight I took in/out of TUS began/ended in PHX on US a few years back.

Has there EVER been a scheduled commercial flight within Delaware?

This is interesting - I think my list is as follows:

• Texas - AUS-DFW, AUS-IAH, AUS-HOU
• Georgia - SAV-ATL
• Florida - MIA-MCO
• Hawaii - KOA-HNL
• California - LAX-SFO

Several people have mentioned flights from VA airports to IAD. However, DCA is actually in Virginia as well. I've done RIC to IAD, ORF to IAD, and ORF to DCA.

DL served Wilmington, Delaware in the mid-2000s, in part so they could advertise themselves as "serving all 50 states."

that was UA's promo also ... didn't last particularly long

Allegheny served ILG the same era as Eastern. I remember the two check in areas. According to wikipedia AA and TWA were the first airlines to serve ILG which I find amazing.
