I have a return trip out of LHR connecting in IST on 23 May coming back 1st June. This is becoming unviable now due to the hotel quarantine requirements.

Any thoughts on if / when TK may start cancelling LHR services? I’m ok with the voucher but I’m thinking I should hold on for now in case there’s a cancellation and a full refund without penalty (all sectors booked in J class which allows cancellation but there’s a penalty - don’t remember what it was but a few hundred quid I think)
