In the current climate does anyone have any views on if there any advantages or disadvatages in booking a Codeshare with any of Virgins partners, Delta, KLM, AirFrance rather than a booking direct with Virgin?
It depends what you mean in “the current climate”.
I have a few immediate interpretations, if you mean around covid and restrictions and needing to change things, then I think you need to check the Covid travel page on each of their websites for their policy, but bare in mind it will be driven by the country of that carrier. So there could be nuances that may apply in a British context that might not work or be beneficial to Air France’s restrictions.
My other interpretation is one around the company going bust? I don’t really see this as risk anymore, VS have come this far, forward bookings are good, they are buying aircraft and the recent raise of capital was used to partially pay down debt. Other than standard protection - booking with a credit card etc, I don’t think you need to do anything else.
