It looks like VS already have as the COVID-19 re-book
page appears to have been updated since I last looked at it.
The table of the various dates when you booked your ticket has now been replaced by what now looks like a blanket waiver.
Also the fare difference when you come to re-book bit has been updated as well.
If you book before 31 Dec 2020, for travel all the way up to 31 Aug 2021, we’ll waive the change fees (for up to two changes or one name change) if you choose to amend your booking. You can rebook to travel anytime before 31 December 2022.
If the difference in your new fare is within £60 in Economy, £120 in Premium, or £350 in Upper for a round trip*, we’ll waive the additional cost so you don’t pay more than for your original ticket.
If the difference in your new fare is more than £60 in Economy, £120 in Premium, or £350 in Upper for a round trip*, we’ll reduce it by those amounts. For example, if your new fare is £100 more than your original ticket in Economy, you’ll only pay the £40 difference.
If your new fare is lower than the original fare you paid, then we’ll refund the difference.
*For one-way trips, 50% of the respective amounts apply
It’s important that you make any changes before the date you were originally due to travel, otherwise we won’t be able to amend your booking.
If you’ve booked through Virgin Holidays, or through another website or travel agent, please contact them directly for your options.
Changes to cabin or destination will result in the full fare difference being payable. This policy does not permit refunds, your original fare rules will apply.
This policy applies to all ticket types (including those that would normally be non-changeable) and all booking classes (including Economy Light) on all routes in Virgin Atlantic’s international network, and for tickets booked with us on our codeshare flights including on partners Delta, Air France and KLM. Your flight number will begin with the letters "VS". It also includes Flying Club redemption bookings.
I presume where it says 'If you book before 31 Dec 2020...' applies to all existing bookings as well?
