Does anyone know if British Airways provides PJs in Business Class? (I am flying from Toronto to Heathrow)

In our experience we have not been given PJ's in business class. We were bumped to first once and got them.
We have been on that flight (TO to Heathrow) several times. We use the BA lounge before and have dinner before the flight in the lounge. (You can even eat again on board if you want.)

Not in my experience

Not on the flights sydney to london and return last May and June.

PJs are in First. If you can, try to get a seat assignment in the Upper Deck (if you're on a 747)... The rear-facing seats by the window are fine, plus you get all that shelf space to put your junk on.

Having flown Toronto to LHR in Busiess class about 16 months ago, no PJs.

I pretty much thought the whole thing sucked. You 'eat' your meal in the BA club before hand, that is, if you like buffet.

Because of a family of 8 in Business class where they had an unruly child of about 7 years old, that they just ignored, the whole trip was not fun. I am normally quiet, but I did join in on the shut that @#$% kid up. The parents must have been on drugs, because they didn't seem to listen to anyone, flight attendants included.
