I only visited Heathrow Three or Four times in 2019. Mostly because it is a Two and a half hour journey for me and when it was sunny, I would be working. However, I did manage a few reasonable photos.
It is notable that all the photos are now only of Boeing or Airbus machines and within those the A350 XWB, A320 Neo's and B787's are more and more prominent. British Airways provided us with Four specials for their 100th celebrations, Eurowings sent in a few specials, Air Belgium were subbing for BA, Gulf Air have a new scheme as do ElAl. The Gulf Air retro sadly was a late afternoon shot and therefore not so good as indeed was the Turkish Airlines A330.
