I am hoping I will be in luck to be able to travel to UK this July. I feel things may not be best but will airports be open for me to fly?

I leave July 4 get to Heathrow, London July 5. I am really hoping my trip won't be cancelled for me. I really care for my summer trip especially July is my favorite month in UK. I hope this coronavirus does not get worse. I heard some people mention they got an email from their airline saying we will refund you if traveling before May 31. I am flying British airways from USA to England this July and do you honestly think things will get better by July. I know if I flew April or May it does not look good at all but I am hoping July won't be bad. Please let me know what you highly think. I would appreciate very much. Thank you
