LONDON (BLOOMBERG) - Airlines, passengers and businesses scrambled to respond to a deluge of travel restrictions announced over the weekend to slow the spread of the Omicron coronavirus variant.
An initial spate of flight bans from southern Africa, where Omicron was first detected, gave way to more wide-ranging measures that will make travel more expensive and less convenient - if possible at all - recalling earlier days in the pandemic.
Britain re-introduced mandatory polymerase chain reaction (PCR) tests for all arriving passengers and said they must self-isolate until receiving a negative result. Israel closed to all inbound foreign nationals for 14 days, the Philippines said travellers from European countries including Switzerland and the Netherlands will not be welcome for several weeks and Singapore delayed the launch of vaccinated travel lanes with Qatar, the United Arab Emirates and Saudi Arabia.
Spain and Switzerland tightened access for arrivals from Britain, whose travel comeback has quickly been thrown into reverse. British low-cost carrier EasyJet said on Sunday its flight schedule was operating as normal, "however we continue to monitor the situation closely".
While the full impact will get clearer over coming days, "this will be problematic for business travel - particularly inbound into the UK", said Mr Martin Ferguson, a spokesman for American Express Global Business Travel.
Organisers of the World Aviation Festival in London told attendees the event will go on as scheduled starting on Tuesday, the day the new British rules come into effect. The group arranged for testing at two nearby hotels where delegates who are guests can self-isolate while awaiting results.
A separate, internal corporate event in Britain was shifted to hybrid from in-person, because the new testing and isolation requirements would have caught out some attendees set to arrive on Tuesday, according to a source.
Leisure travel will also see an impact, while friends and relatives visiting loved ones after long absences are more likely to go through with a trip, said Mr Alex Irving, an analyst at Bernstein in London.
"Christmas bookings will obviously be weaker than we had expected prior to the omicron variant," he said. "As you add barriers to travel such as the PCR tests and isolation requirements, all that does is changes the incentives."
Airlines now face a return to the uncertainty of shifting rules and public health developments that threw customer plans into chaos and undermined demand earlier in the pandemic.
British Airways, for example, halted flights to Hong Kong through at least Nov 30 after one employee tested positive for Covid-19 and staff were sent into quarantine. The airline said it is keeping its operations under review as the situation evolves. Singapore and Japan are among countries that have said they are considering tighter border restrictions.
The risk of a second lost winter has already tanked shares of airline stocks, with the Bloomberg EMEA Airline Index down 18 per cent this month. This will make it harder to raise fresh capital to repair balance sheets - British Airways parent IAG has €12.4 billion in net debt, for example.
"This comes at a time of year when airlines will seek to bolster liquidity and to a modest extent profitability, and is after an already arduous 18 months of revenue depletion," said Mr John Strickland, who heads London-based JLS Consulting.
