A fundraising page, set up by BA cabin crew colleague Stephen Crook on New Year’s Day, had raised just shy of £40,000 as of 8.30am on Thursday (2 January) via nearly 3,000 donors.
"On New Year’s Eve, we lost three fellow mixed fleet crew in a fatal car crash, and another is in hospital in a serious condition," wrote Crook. "I have set up this fund to raise money for the families of the four crew members involved.
"I don’t know if I knew these individuals personally, but at mixed fleet, we are all one large family and when times are tough, we pull together and look out for one another like no other family can."
Crook added he had approached BA for help liaising with those families affected to distribute the funds. "I know it is January and I know money is tight but I know that as a fleet, we will pull together and make this happen," said Crook. "Rest in peace guys, go fly the skies eternal."
Nearly 500 tributes have been paid via the fundraising page, with comments flooding in from fellow cabin crew staff and members of the public.
Sharon Treanor Boyle wrote: "My heartfelt condolences for all of those affected by this terrible tragedy. I am BA crew and we are always there for each other like one big family. Fly high angels, gone too soon under terrible circumstances."
Alan Jansen Lage added: "I’m worldwide crew and deeply saddened by the loss of our lovely colleagues, especially at this time of the year. My heartfelt love and sympathy goes out to their families and loved ones – no words can take away such pain."
