OneWeb as currently conceived is an already-bailed-out, strongly politicized, weak version of Starlink V1.There is a good technical case for an integrated GEO/LEO system. You can offer global service pretty much immediately from GEO and then build out your LEO gateways to offload the traffic in higher-density areas. This would require suitable terminals and a fair amount of software. I have no idea if OneTelsat (EutelWeb?) could or would try this.Maybe, but no idea if the constellation densities required are worth it, or the threshold user densities for LEO-on-GEO backup to be worthwhile plausible, given megaconstellations aim for isolated, low-density traffic - not to mention the latencies offered would wildly vary.

Very low density, hard to support from LEO without ISL, but when the plane reaches an area covered by LEO it no longer uses the highly-constrained GEO bandwidth. This more or less works for ships other than cruise ships also. Yes, the latencies vary wildly, but any connectivity is better than no connectivity. On a typical over-ocean airline flight, there would be one transition from LEO to GEO after takeoff and one transition from GEO to LEO before landing, so latency "varies wildly" twice during the flight.
OneWeb already gave up on that, but not SpaceX.I don’t know what you’re talking about with respect to airline difficulties, except temporary due to fuel costs and COVID. On a long term trajectory, airlines (Western and otherwise) are growing and growing.
Many non-Western airlines will be barred from operating with Starlink, either "softly" or directly, à la China or Russia.

Maybe India.Looking at the Starlink's own future country coverage map, these are the only countries which aren't planned being covered:Syria, Iran, Afghanistan, China, North Korea, Russia, Belarus, Venezuela, Cuba. The rest of the countries seem to have a planning date, except: Pakistan, India, Thailand. Not that many countries for possible Eutelsat/Oneweb-only access.

Because of the UK government's stake the @EU_Commission continues to regard @OneWeb with "greatest suspicion" even after the proposed @Eutelsat_SA merger, therefore is still pursuing @ThierryBreton's L€O set to be operational by 2027.https://www.challenges.fr/entreprise/aeronautique/fusion-eutelsat-oneweb-la-commission-europeenne-loin-detre-emballee_822316
.@Europarl_EN's rapporteur for L€O, @GrudlerCh, states that @OneWeb is incompatible w/ EU's LEO ambititions due to British veto rights & foreign ownership, EU must be master over its sats, claims OW is inferior technologically to L€O & would reduce opportunties for EU industry.
I'm a little delayed with my monthly #SOCRATES conjunction analysis (bc I have been unwell) but as a teaser here is a chart showing the daily conjunction rate (Pc >= 1E-5) for #Starlink & #OneWeb as a function of the # of satellites in each system (active or failed).https://twitter.com/ProfHughLewis/status/1557382970377469952
