Whilst the UAE may be off the UK quarantine list, the UK is locked down until 2 December and whilst 1.2 million Brits visited last year, many of them would be 3 night stopovers on the way to somewhere else.
There could be some demand over the northern hemisphere winter for a sunny, COVID free destination and Dubai has plenty of attractions and cheap hotel rooms. However, as a destination in its own right it won’t be filling A380s and B777s, EK needs the long haul transit traffic it was designed for and that won’t be back until sometime after a vaccine is in widespread use.
SQ is grounding the A380s and most of the B777s for around the next 12 months and will be operating B737s, B787s and A350s. CX are grounding many of their B777s and are going A321/A350 and don’t want the B777-X until 2025. EY has abandoned plans for world domination and is becoming a medium sized airline. QR have grounded the A380 and may not bring it back.
