Yes. RAF bomber command was probably the premier air force in doing this. By 1944 they would have typically:

Put up a Mandrel screen across the North Sea to blind German search radars while their aircraft became airborne and formed up.
After crossing through the Mandrel screen ABC and Jostle radio jammers would have begun to literally make German fighter communications virtually impossible.
There would be several diversionary strikes using jamming to look like big bomber groups.
The main strike(s) would have jammers aboard to blot out search and fire control radars for flak as well as night fighter radar. The group would begin to drop chaff as they approached the German coast in huge quantities.
British night fighters would prowl using systems like Serrate to track down German nightfighters that ran their radars.

The US would have had large numbers of Carpet and Rug jammers along with Chaff to jam German flak radars. The US didn't worry so much about fighters and direction as they operated in daylight making this largely irrelevant.

The Germans would return the favor operating ground jammers that made it hard for the bombers to use systems like Gee or H2S for navigation.

As Adolf Galland himself said to Göring in mid 1944 "Today the nightfighter achieves nothing! The enemy's jamming blots out all electronics leaving us blind!"
