We flew into LHR T-4 on a UA flt from IAH which was scheduled to land at 9:30 am but was a little late. We had to collect one bag from baggage claim and then made our way over to Terminal 5. We arrived at Terminal 5 at 10:30 am 40 minutes prior to our LHR-MAD flt scheduled to leave at 11:10 am.

- Yes, we were on separate tickets.
- We bought the LHR-MAD ticket on Travelocity and were told that we could not get boarding passes until we arrived in LHR. (I called BA several weeks before the flt to check this point.)
- We flew in from the US and landed in T-4 and had a tight connection to get to T-5. It is not as if we just turned up to LHR late.
- Even if checking in 40 mins prior to take-off is late (not sure where this is written), it seems that as a common courtesy BA could have let us go standby on the next flt to MAD without charge. The flight was half-full and there was no way they were going to be able to sell all the seats at that point.
- It feels like BA basically extorted $600 from us.
- And now BA Customer Service is uncontactable. No one answers the phone no. listed on their website and when I call BA's reservations no. to ask for help, I am told to send a message via BA.com (which I have done twice and no one writes back)
- And yes, I have disputed this charge with my credit card company.

Any thoughts on how to reach the elusive BA Customer Service people?
