Hi Omar
If you're only coming to the UK for the match you should wait until the matches being shown on TV have been announced before booking flights, as the time of those matches will change. The dates they are suppose to announce the changes are here but they are often late: https://www.premierleague.com/news/4039904
You will have no problem at all getting tickets for Southampton and Ipswich on general sale as we are playing badly and will probably be relegated by then, but you're welcome to send me a message if you get stuck.
