Many here will be aware of considerable speculation that Portugal will be put back onto the quarantine list by the UK later this week. Air fares for Portugal-UK seem to have risen much more than UK-Portugal, with a peak fare for returning to the UK on Friday, just before the expected deadline for return without quarantine, suggesting people are taking this seriously.
This is perhaps unfortunate for airlines which have recently added flights on UK-Portugal routes. There has been discussion above about Sweden going onto the UK's 'permitted' list. If this happens, do people foresee airlines adding capacity to UK-Sweden routes, while possibly dropping a few UK-Portugal rotations ?
