I could not find where to go at the airport. The flight was under Are Lingus, but operated by BA. Only BA had a counter at Denver Airport. Just a small comment. Also, I didn’t know where to get my seat info. The Are Lingus flight did not have it. They were assigned. Expedia website also did not have it. Please, Expedia, add links to the for the airlines. You used to have them - what happened. That should be part of the check out process when buying. It should not be a thing we do AFTERWARDS, weeks later.

Rear coach environmental (air temperature) systems on 747-400. Not enough air flow for cooling. Very warm temps throughout flight.

There was a mix up with our prepaid baggage so I had to pay twice. I’ll be contacting Expedia reps after my vacation to sort this out. Other than that, British Airlines did a great job.

With limited seating space, I wish the seats wouldn’t recline so far
