London Heathrow Airport is likely to miss an extended deadline to finish installing advanced security scanners, according to people familiar with the matter, raising the prospect of peak-summer backups as passengers take time to remove liquids and electronics from their luggage.

The UK’s biggest airport is exploring options for another extension beyond June, said two of the people, who requested to remain anonymous as discussions were confidential. Other airports also risk going over the cutoff, one of the people said.
